Thursday, September 21, 1944 www.onwar.com

On the Eastern Front... The Polish 1st Army is forced to withdraw from its bridgeheads in Warsaw.

On the Western Front... Operation Market Garden continues. The British 30th Corps attacks northward from Nijmegen but makes limited progress due to German counterattacks and the exposed terrain. In Arnhem, forces of the British 1st Airborne Division are forced out of the town but remain north of the Rhine. A Polish Parachute Brigade is dropped two miles south of the British position, on the opposite side of the river.

In Italy... Elements of British 8th Army reach Rimini. Canadian and Greek forces capture the town.

In the Philippines... US Task Force 38 conducts air strikes on Japanese targets on Luzon, particularly Manila and Manila Bay. Twelve American carriers are involved.

In Occupied Denmark... The general strike protesting recent deportations by German authorities comes to an end.
