September 20 - Lublin falls at last

Lublin, one of the last Polish free cities outside Warsaw falls into German hands. Poland’s capital continues to be bombed by the Luftwaffe and bombarded by the Nazi artillery.

In the Western front, Royal Air Force and the Luftwaffe clash for the first time. In the border between Germany and France, Messerschmitt Me109s attack a squadron of Fairey Battle bombers. The score comes to 2 British planes down against 1German.

At sea, as the convoy system begins in the North Atlantic merchant routes, Allied navies become more aware of the submarine menace. On this day, the second U-Boot, the U-27, is sunk by depth charges from the HMS Fortune and HMS Forester.
