- That this program was to cost more than $430,000 was one sign that
- starvation rations were a thing of the past. As had not been true for many
- years, money was coming in plentifully. During the fiscal year 1941 the
- Signal Corps Laboratories, for example, were able to grow five times as big as
- they had been in 1940. In April the Signal Corps submitted its contribution
- to the general augmentation of the Mobilization Plan, in which the basic
- assumptions now were that the mythical M Day would occur somewhere during the
- last three months of 1941 and that everyone in the Army as of that date would
- stay in. The Signal Corps School and Replacement Training Center, steadily
- preparing the communications technicians for the growing forces, estimated
- that they would be coming out of the thirteen-week and sixteen-week hoppers
- at a rate well over 500 every Monday. Two summer months alone were expected
- to turn out nearly 6,000.
-
- Expansion was of course too recent to make its effect felt immediately.
- There was a lag in the developmental field, and an even longer one in
- procurement, which nothing could reduce. Planners in the Office of the Chief
- Signal Officer asked for a month's warning on the mobilization of division
- signal companies, knowing it to be very likely that ostensible "refresher"
- time would have to be devoted to giving many of the men their first
- acquaintance with communications work. And until the Laboratories could
- perfect replacements and the factories produce them, the equipment and the
- trickle of procurement of the years just past had to suffice. Such items as
- were on hand were parceled out among all of the branches calling for them;
- many became controlled items and were distributed only under a system of
- priorities, although they might go back in date almost to World War I. All of
- the new items were on the way, some so far from development that their
- ultimate manufacture was barely discernible, others slipping so easily from
- one stage to the next that there was even a chance that they might be ready by
- the time that World War II drew America in. Despite the sudden flush of
- relative wealth, the Signal Corps could not at once heap its partners-at-arms
- with abundance; but their needs were uppermost, development having advanced or
- started in a hundred directions, and procurement in a dozen.
-
- In October and November of the preceding fall, the Cavalry and the Signal
- Corps had agreed upon a short-range radio to be constructed, with its antenna,
- around a golden staff; the trooper would hold it upright with the lower end of
- the staff resting in a saddle boot. This golden radio, the SCR-511; was to
- become one of the best of the walkie-talkie types although not much used by
- men on horseback. Rather, it proved out as a set for cavalrymen and
- infantrymen alike and engineers as well, all of whom used it in vehicles if
- they could, as a pack set otherwise. But at the same time that cavalrymen
- approached the Signal Corps for this portable golden set, infantrymen had
- asked for an even more portable and compact, equivalently short-range radio
- for paratroopers to use. On this, the development was phenomenally rapid. By
- mid february the Galvin Corporation demonstrated equipment which filled the
- bill. Weighing only five pounds, and promptly accepted in substantially its
- original form, it became the SCR-536 and probably the best-known equip-item of
- all Signal Corps treatment in the war: the handie-talkie. The initial order
- to Galvin, later that year, was 3,500 of them.
-
- The Laboratories were also progressing with the Armored Force "500" sets.
- The first models of the SCR-509 and 510 had arrived at Fort Knox, and the
- Armored Force gave them a thorough drubbing to make sure that they were
- sturdy. A motorcyclist with a 510 on his machine ended a two-hour ride in a
- severe spill which injured the man, damaged the motorcycle, and left the radio
- unaffected. This was proof not so much of the set as of the mounting by which
- it was held to the luggage carrier, for a second SCR-510 attached without the
- special mounting was all but shattered. Yet a third, similarly without
- shockproofing, survived being thrown to the ground from a scout car by a very
- heavy jolt and, reinstalled in the car, worked perfectly.
-
- So two more 500's were on their way. Others were already part of the
- Armored Force organization. As it was planned, each tank had both a radio and
- an interphone system. With headsets at their ears and microphones at their
- throats, crewmen could intercommunicate and intracommunicate. In a regiment
- of 108 tanks, all would have interphone equipment, just as in a bombardment
- airplane, and the company commanders would have SCR-508's (a transmitter and
- two receivers), battalion and platoon commanders SCR-528's (a transmitter and
- one receiver), and all the rest SCR-538's (receivers only). A model of the
- tank under procurement for this purpose, the new medium M3, went on display at
- the Aberdeen Proving Ground in April for the scrutiny and comments of
- representatives of the Air Corps, the Signal Corps, and the Ordnance
- Department.
-
- W-130, the light assault wire, posed a problem if it were to be
- manufactured in mass quantities. It required a special latex insulation for
- which a single manufacturer controlled the patent. The answer was to spread
- the patent. This the owner agreed to do; under educational orders, two other
- companies joined his in the W-130 manufacture; the Defense Plant Corporation
- built the factories for all three; and the result was a ready potential of
- 6,300 miles of the wire a month.
-
- Introduction of the teletypewriter at field maneuvers had accented a
- different side of the wire question. The Army needed a cable which would
- combine the long range of open wire, strung on poles, with the ease of field
- wire, which did not possess the range but was speedily laid. The need was
- filled in time to meet the approaching demands of field teletype for just such
- characteristics. In this case, the solution came from the Germans,
- unwillingly. British Commandos had just captured some new cable and under the
- agreement reached in the course of the Tizard Mission sent samples of it to
- the Signal Corps Laboratories. This became the renowned spiral four, a
- superlative cable consisting of four insulated conductors wound spirally about
- a central core.
-
- As for the instruments which the wire served - the telephones,
- switchboards, and teletypewriters which the past year's maneuvers had thrown
- into a sharp, clear light - they were the center of the stream of supply to
- the ground forces, becoming so usual, so abundant, so effortless that they
- would be more and more taken for granted the more they approached their goal,
- imitation of the human voice and eye. By this time the Signal Corps
- Laboratories had largely completed work on the sort of switchboards which
- Colton and Reeder had pointed out as the most urgent of tactical
- communications needs in 1939 and 1940 maneuvers: 100-line BD-80's which could
- handle heavy traffic and yet operate simply, from the modest power sources
- likely to be available in the field. These now began to reach the Infantry.
- The new corps and division switchboards did not; and in the area where
- Infantry communications were Infantry communications, the Laboratories
- altogether forewent the development of new switchboards.
-
- Many things had to yield to the radio and radar developments, and the
- small switchboards were among them. Although the two decades in which BD-
- 71's and 72's had been in use had not wholly outmoded them by any means, the
- Infantry Board was undeniably right in saying that they could both be
- materially improved. The chief disadvantage was their weight - 60 pounds for
- one, seventy-nine for other. There was too much else to do, however, and
- supplies of the BD-71 and 72 ran into the thousands, and manufacturers long
- used to making them could turn out thousands more upon demand. Moreover,
- having reached maturity long before, wire held its ground against change to an
- extent which was out of the question for radio. Major O'Connell demurred at
- "burdening the fighting troops with at least twice the switchboard weight"
- necessary, and protested that "repeatedly since 1920 the development of a
- better switchboard unit has been put off"; but since the Field Artillery was
- relatively satisfied and the several arms which used the boards were not
- entirely agreed upon the characteristics of a replacement, the work continued
- to be put off in favor of more vital research.
-
- In any event, by the onset of the maneuver season, it was evident that
- field teletypewriters were on their way to becoming standard tools of military
- communication; and though they did not take the place of a good telephone
- switchboard system, they were superlatively welcome in their own right. An
- observer at the VII Corps maneuvers declared that "the telegraph printer is
- beginning to get the distinction it deserves. Seventh Army Corps kept the six
- . . . machines in constant operation." The old telegraph suddenly was
- revitalized. The new equipment made it possible once again to write over
- wires at a speed equal to the demand of military operations, and without much
- more inconvenience or loss of time than would be true of talking over a
- telephone. As usual, maneuvers were providing a good school for tactical
- training and a good testing ground for tactical supply, research, and
- development. The longer the nation stood aside from actual war, the better
- the opportunity for a Signal Corps to judge itself. The first 1941 exercise
- occurred off Puerto Rico between January 25 and February 14. The Navy and
- Army joined in a problem to test an assault upon an island; Culebra, which
- lies just east of Puerto Rico, was chosen. Maj. Francis H. Lanahan, Jr., the
- Signal Corps observer at the exercise, noted that "it was immediately apparent
- that the Army contingent had not brought sufficient radio personnel" or the
- right kind of equipment, and laid the blame upon Admiral Ernest J. King for
- having imposed his own plan without consulting or informing the Army in the
- least.
-
- This was irksome but not conclusive, for it was still possible to
- distinguish the terms in which the Signal Corps ought to be thinking. The
- signal teams, with which the Army element, the 1st Division Task Force, was
- provided, might better be replaced by a regimental headquarters company,
- Lanahan felt. These teams had signal flags, panels, tactical wire, and radio.
- The semaphore flags would have helped to dispel the initial confusion on the
- landing beach had the men been practiced in them; their usefulness in the
- ensuing war developed in just that way. Panels did not prove out, although
- the slow airplanes of the day made them look feasible at this time, as did the
- accustomed use of aviation as a sort of sky cavalry. Wire equipment,
- including the new W-130 assault wire, was satisfactory. Radio SCR-131's and
- the preliminary walkietalkies, the SCR-195's was less so, but without any
- basic fault attributable to radio itself. The 131's were out of date by many
- years, and porcelain antenna insulators in the 194's and 195's were easily
- broken. Modernization amended one and phenolic insulators the other. The
- uninterrupted trend toward radio left no doubt that it was welcome everywhere;
- in all of the maneuvers of 1941, it came into far more use than in 1940.
-
- The war in Europe and the 1940 maneuvers, particularly the one which had
- involved the First Army and the IV Corps in November, prompted Lt. Gen. Walter
- Krueger to wish plenty of radio on hand for the maneuvers of his Third Army in
- Texas, where he took command in the spring. He wanted to blanket every part
- of his force with radio communications the advanced reconnoitering elements,
- the reconnaissance airplanes, the command posts, and also that he might move
- freely without losing touch with any unit of his command. In order to bring
- this about, his signal officer, Col. Spencer B. Akin, went so far as to write
- out of channels for three SCR-193's, which neither the Third Army nor the 52nd
- Signal Battalion had been authorized to have. The SCR-193 was a controlled
- item, short in supply; so that the best General Mauborgne could give him was
- advice to make sure that the next table-of-basic-allowance rests included
- them. Working for the ground forces was a two-way business. The employer had
- to make his needs clear. "Without exception," according to two Field
- Artillery officers at the Second Army maneuvers the next month, there was an
- undeniable shortage of radio sets. (Without exception, it would continue,
- until production caught up with demand halfway through the war, and despite
- strenuous efforts to overcome the deficiency sooner.) There was also a want
- of spare parts, but piecemeal issue contrarily encumbered some units although
- in the case of a regiment which had thirty-two SCR-194's, all incomplete,
- excess was no boon.
-
- Lt. Col. Fred G. Miller, commander of the 50th Signal Battalion, brought
- thirty years of experience to bear when he declared that the tables of
- allowance and organization were both meager, both "too superficial to perform
- the . . . mission of "the signal battalion with the modern army." There were
- not enough enlisted men or officers for a peacetime organization, let alone
- for war, Miller thought. Grades were too few and too low for a technical
- service; and not a day passed that a technician was not taken off to do
- Kitchen police duty. Miller believed that the tables provided for too many
- general cargo vehicles and too few of specialized value. To give a battalion
- only 2 radio and 12 wire vehicles while allowing 55 for cargo purposes was
- "all out of proportion as to numbers and types, and based on no sound
- fundamental plan." Furthermore to put all of them, plus the drivers and the
- mechanics, in the headquarters and headquarters company of the battalion was
- comparable to putting all the guns of an artillery battalion in the
- headquarters and none in the gun batteries. The tables omitted teletype,
- repeaters, and power units essential for a higher headquarters and certainly
- for the self-contained unit he thought a signal battalion should be: so
- organized and equipped that it could load everything into its own vehicles and
- be prepared to set up army or corps headquarters communications without delay.
-
- The Second Army commander threw his weight behind Colonel Miller. Office
- of the Chief Signal Officer responses to him were reasonable; they represented
- simply a difference in point of view. Miller spoke as the man in the field
- charged with a tactical mission. Lawton, who answered him, did so from the
- point of view of the headquarters man, not having to meet a tactical situation
- firsthand as a division signal officer did, but required to cope with a
- general situation broadly, as an officer in the field was not. He called
- attention to new tables which authorized a battalion twenty-four wire and
- four radio vehicles. Several other new types were on the way, all specialized
- to haul poles, to accommodate cable reels and poles together, to serve cable
- repair, and so on. Everything else Miller had mentioned was assuredly either
- under procurement or under study. If it had not appeared in the field, the
- reason was that the Signal Corps policy, learned by its own long experience,
- was not to put any item into the tables of organization and allowances until a
- unit which requisitioned it could be sure of getting it. This left the
- opposition unconvinced but the point had some validity all the same.
-
- The Office of the Chief Signal Officer did agree that far too little
- equipment had been issued to battalions for training, but inasmuch as
- henceforth all of the men for such units were to be learning their signaling
- in the Signal Corps School and Replacement Training Center, that difficulty
- was disposed of. Training in the communications units beyond the point where
- direct Signal Corps responsibility in the ground arms stopped was another
- matter. Certainly the Infantry, the Cavalry, the Armored Force, and the Field
- Artillery would have to see to it that the draftees being poured in to fill up
- their ranks learned on the job, with equipment on hand, the communications
- tasks they were assigned to perform. From the Signal Corps point of view,
- observer after observer at the succeeding maneuvers noted a lag. Training had
- not caught up with manpower. Their reports unconsciously confirmed the
- impression of critics that the maneuvers were a dream play in which
- lackadaisical recruits, drafted for a year, performed by rote motions which
- had never been suitably justified to them or even explained; where "dead" men
- sought the shade of a pine tree, to chew the needles while they awaited the
- umpire; where crudely lettered fluttering cloths labeled a truck a tank, or a
- World War I Springfield a
- .30-caliber machine gun.
-
- In that summer, the Germans had just delivered another heavy blow and the
- Japanese were getting set for one of their own. The signal units at Tennessee
- maneuvers could get no nails, screws, or plywood for their field message
- centers, and chipped in to buy them. Cord was a universal shortage.
- Headquarters provided itself with 20 representative messages, which the
- communications men had practiced often enough to memorize. Some of the Morse
- operators could send as many as 10 words a minute. But not all. The 33rd
- Division had held a five and one-half weeks course which 178 men had
- completed, but in which only 36 had attained a code speed of 15 words. An
- operator who could manage to take in only 15 words a minute at a code
- classroom table could not do much better than 10 under field conditions. Panel
- crews knew the technique of panel communication, but had never had any
- practice with an authentic airplane. The 33rd Signal Company and the 58th
- Signal Battalion both failed in the reading of maps and aerial photographs.
- Yet by specific statement, "the morale, enthusiasm, soldierly attitude,
- willingness to learn, on the part of the enlisted men [were] highly
- commendable." Training had simply not got started.
-
- One device to stimulate it which occurred to signal officers was for each
- corps and division to seek out commercial communications men who might be
- serving in other duties. Col. John C. Moore, First Army signal officer,
- reiterated the concern of Miller, the Second; Akin, the Third; and Col. Joseph
- J. Grace, the Fourth Army signal officer. The Washington Post correspondent
- at the First Army's Carolina maneuvers charged that "radio fell down
- repeatedly, delaying messages which would have changed the course of battle."
- This immediately alerted the Chief Signal Officer. Was it true? It was, said
- Moore. "Our one great fault" - he was speaking of the First Army - "is lack
- of training." He described breaches of radio discipline and inspection, and
- remarked, "I seldom see an officer standing by listening to radio transmission
- to correct procedure." He extended his remarks to take in wire: "I am
- appalled at the great percentage of wire failures due to lack of training in
- its laying and maintenance . . . Some of our officers are seized by panic when
- they are confronted with the need of wire from army to corps and corps to
- division, thinking that the job is too big for us." From the state of
- Washington, and anent maneuvers there in August, Grace disclosed that the
- 202nd Signal Depot Company at Fort Lewis had handled nothing but paper signal
- supplies, a training assignment which did not train. He suggested
- transferring the unit to special duty at the corps area depot in San
- Francisco, where the men could work with real equipment. Lt. Col. Raymond C.
- Hildreth, in the Supply Division of the Office of the Chief Signal Officer,
- disagreed. "To load up one or two corps areas with a field army or more . . .
- is not reasonable. The armies should establish their own depots and necessary
- repair shops."
-
- The Signal Corps had both sides to consider. Making sure of field
- communications was half of a mission whose other half was administrative. The
- corps areas often carried out the administrative duty, especially at a stage
- when the nation's military effort was almost entirely confined to home soil.
- Over much of the face of the country, and possibly in the South more than
- anywhere else, the region of the Fourth and Eighth Corps Areas, the defense
- program was making quick, deep changes. In the industrial East and Middle
- West a general expansion of plants was beginning, in order to take care of the
- production demands of war. Civilian though they were, their purpose was
- military and naturally tapped military services at many points. Huge
- reception or training areas like Fort Dix, New Jersey, or Camp Grant,
- Illinois, were filling, expanding, filling to new limits, and expanding again,
- at a rate which left them perpetually unfinished. Raw settlements for
- thousands were appearing everywhere, panoramas of newly sawn lumber and
- bulldozed land; and in some localities the nearby towns, long saddened by
- economic adversity, were at a loss to cope with them. Depots, arsenals, harbor
- gun sites, and military hospitals made other parts of a scene of unlimited
- emergency; and all bulwarked hundreds of existing posts and stations which, if
- small, were growing large, and if large, enormous. Where the region was
- undeveloped, the Engineer, Quartermaster, and Signal Corps were challenged to
- produce complete systems of roads, sewage disposal, electricity, and
- telephones. There was equivalent work of a different kind in commercial and
- manufacturing areas; meagerness of facilities was not the problem, but defense
- was expanding so many offices and factories that even the most extensive
- systems were taxed.
-
- Funds for the new emergency construction went as a rule to the
- Quartermaster General or Chief of Engineers, who in turn made suballotments to
- the Chief Signal Officer, to cover the cost of the telephone part of the
- construction plan. This the Wire Section of the Plant and Traffic Division
- prepared, and ordinarily delegated its execution to the signal officer of the
- corps area concerned. Telephonically, the term plant refers to the mechanical
- apparatus, taken as an entity, which the process requires. At times, signal
- officers rented the plant for a defense project intact from the local
- telephone company; at other times, Signal Corpsmen entirely installed and
- maintained it. The decision which to do was taken upon the basis of
- long-standing practice. Just as in Adolphus Greely's days in the frontier
- West, the Signal Corps did not go where commercial systems were already
- established and install competing systems, but rather went where they were
- not: a direction which implied commercially unrewarding or pioneer and rugged
- circumstances, and a purpose for which the Plant Engineering Agency was
- created later on, in the war.
-
- The expansion going on as of midspring of 1941 called for $5,594,150
- worth of telephone plant, especially in the Fourth and Ninth Corps Areas.
- Seventy-seven of 213 projects all told were for Air Corps installations. The
- rest were all for the Ground Forces, in the various guises which defense
- expansion took. Mushrooming troop housing called for 59, almost evenly
- divided among new posts, old posts, and replacement training centers. A
- program of 26 projects was scheduled to supply telephone service to Ordnance
- and Chemical Warfare facilities. For the Medical Department there was a list
- of 10; these were to serve large hospitals, of a thousand-beds or more, which
- it was agreed ought to have plants separate from the general post switchboard.
- Storage depots, reception centers, special facilities of all kinds needed
- consideration. The cable plant for harbor defense, for example, amounted to
- three or four times what was normal for the same number of telephones in a
- different activity. The conduct of fire, particularly of the great fixed
- guns, necessitated constant communication between the gun crews and the
- observers or spotters. These were not the conditions which radar would bring
- about, but radar was not yet established in most Coast Artillery stations.
-
- When there was an occasion to join Army with non-Army areas, other
- agencies of the government were involved and other considerations entered than
- those of the Signal Corps, G-4, a corps area, and the Bell System. When
- $868,250 for switchboard and telephone construction in defense-housing areas,
- included in the Signal Corps 1941 supplemental estimates, was cut to $75,000
- by the Budget Advisory Committee and restricted to guard and fire-alarm
- telephones, straightening the matter out called in the Federal Works Agency
- and the Public Buildings Administration. This situation was usual, not
- unique; and the increased intertwining of the national interest with the
- military was to make it universal. In the face of the demands of defense
- housing, a working agreement and mutual understanding were highly important.
- Many of the commissioned and noncommissioned officers of a rapidly growing
- post had to live in a defense-housing development, whereupon the question
- arose of connecting them by telephone with the post itself. A commander could
- think of many situations when it would be inefficient, and of some when it
- would be serious, not to be able to get in touch with the post complement
- during off-duty hours. In all instances where the defense housing stood on a
- military reservation the Signal Corps simply gave the Bell System blanket
- permission to install home telephones and connect them, over Signal Corps
- poles if necessary, with the nearest commercial exchange - not, of course,
- with the post system, although in many cases the use made of the two was much
- the same.
-
- At a camp or post it was also important to have adequate public telephone
- service. Off-duty use of the public telephone was especially high at
- reception centers and training stations. Men wanted to call their wives and
- mothers, and, since most of them were on duty during the day, they needed to
- have phones available to them between evening mess and tattoo. They preferred
- booths, too, rather than the publicity of a telephone on an open wall.
- Nevertheless, it was often impossible to be sure that morale was served as it
- ought to be by plenty of booths and phones. The Bell System estimated from
- its reports of usage that three or four per thousand men would take care of
- the demand, but long queues were a regular occurrence at the evening peak; and
- when movement orders were out, the rush to the telephone became an elemental
- force. At most posts at 129, up to that time, the men also had access to the
- public telegraph, Western Union or Postal or both, so that the strain was
- partly shared by the older commercial facility. Part of the task in analyzing
- any request for a telephone project lay in discovering whether existing
- equipment was actually being used to the maximum, as the circumstances
- unquestionably required. A post signal officer might unwittingly be allowing
- inefficiencies because he was new to his job and unfamiliar with Army
- procedure. From time to time, he perhaps might send in requisitions in round
- numbers, almost a sure indication that some of the order would be left over.
- At some posts, the drive to expansion created temporary or deceptive demands
- which soon evaporated but still withheld telephones from active use. With the
- adoption of new standards, there was always a tendency to get rid of
- everything except the newest equipment, despite the fact that much which was
- of substitute or recently obsolete quality was good enough. Signal officers
- turned in serviceable EE-5's and BD-9's and 11's even when depots were unable
- to provide the models intended to replace them. To all officers in this duty,
- the Chief Signal Officer sent out word that they ought to check to see what
- excess equipment there might be, to recondition it, put it on inventory, and
- send it to other posts where there was a shortage.
-
- Most post telephone systems contained three parts, the main one being the
- central administrative switchboard and the other two being comprised of a
- target-range system and an emergency system for reporting fires and
- explosions. The fire department, the motor pool, the commanding officer, the
- officer of the day, and the post physician could all be alerted from the alarm
- system, which was essentially a conference circuit that the operator kept open
- as long as was necessary. A specific type, which became necessary with the
- building of cantonments housing 50,000 men or more, reported all fires to the
- central fire station and made it possible for remote guard posts to report in
- to the main guardhouse. Target-range systems varied from a modest support for
- rifle practice to 100-line separate switchboards with telephones scattered
- throughout the target area and connected by tie lines to the main system of
- the post. This central administrative post telephone system was itself either
- small or large according to the size of the camp. If it went above 500 lines,
- every effort was made to install automatic, dial equipment. Usually the
- outside plant was lodged underground, although at any impermanent post the
- wire was simply strung on poles shared with the electric lighting. In the
- spring of 1941 there were 189 administrative post telephone systems with
- 60,000 telephone connections, and by the time that all of the temporary
- additions then in view were completed, there would be 274 systems and 125,000
- telephones.
-
