July 15th, 1940

With the destruction of the BEF in France, England is vulnerable to a invasion by 
the German Army. The Luftwaffe has achieved air superiority over southern 
England. This has allowed us the chance to launch Operation "Sea Lion", the 
invasion of England. Your orders are to secure  a beachhead near Dover. If you 
succeed in your mission, follow up waves of German Panzers will be able to 
breakout and take London. Your success could mean knocking out England out of 
the War. Latest intelligence reports indicates that you will be facing a mix of Home 
guard and regular units. Remnants of the RAF many interfere with your landings.
