1 Dollar - Elizabeth II Battle of Britain

The Battle of Britain lasted from July to October 1940, the first major military campaign fought entirely by air forces. The RAF's Fighter Command was critically outnumbered throughout, and the Luftwaffe came closest to breaking it in late August and early September, when airfields and radar stations rather than cities were the primary targets — a strategic focus the Germans abandoned just as it was working.
