1918 the lost battalion

The Lost Battalion is the name given to nine companies of the United States 77th Division, roughly 554 men, isolated by German forces during World War I after an American attack in the Argonne Forest in October 1918. Roughly 197 were killed in action and approximately 150 missing or taken prisoner before 194 remaining men were rescued. They were led by Major Charles White Whittlesey. On 2 October, the division quickly advanced into the Argonne, under the belief that French forces were supporting the left flank and two American units including the 92nd Division were supporting the right flank. Unknown to Whittlesey's unit, the French advance had been stalled. Without this knowledge, the Americans had moved beyond the rest of the Allied line and found themselves completely cut off and surrounded by German forces. For the next six days, suffering heavy losses, the men of the division were forced to fight off several attacks by the Germans.

The battalion suffered many hardships. Food was short, and water was available only by crawling under fire to a nearby stream. Ammunition ran low. Communications were also a problem, and at times they would be bombarded by shells from their own artillery. As every runner dispatched by Whittlesey either became lost or ran into German patrols, carrier pigeons became the only method of communicating with headquarters. In an infamous incident on 4 October, inaccurate coordinates were delivered by one of the pigeons and the unit was subjected to "friendly fire". The unit was saved by another pigeon, Cher Ami, delivering the following
WE ARE ALONG THE ROAD PARALLEL OUR ARTILLERY IS DROPPING A BARRAGE DIRECTLY ON US. FOR HEAVENS SAKE STOP IT.

Despite this, they held their ground and caused enough of a distraction for other Allied units to break through the German lines, which forced the Germans to retreat.
