The 100 Days: Fifth Battle of Ypres. September 28 to October 2, 1918.

On this day in 1918 the Groupe d'Armees des Flanders, a combined British, Belgian and French command, launched an assault at 05:30 after a three hour artillery bombardment, oer a wide front near Ypres.

The assault yielded immediate successes.  Many well known locations that featured heavy fighting earlier in the war, such as Passchendaele, were regained.  The advance continued on through October 2 when the Germans brought up reinforcements and the Allies outran their supplies, and therefore halted.

Showing the direction of things to come, the British and Belgian forces received 15,000 rations by air. That is, air drop.  They were parachuted in.

The battle, like the earlier one at Passchendaele, freakishly featured a lot of rain.
