Erwin Russell Bleckley was a United States Army aviator during World War I, and posthumous recipient of the Medal of Honor, killed in action on October 6, 1918, near the "lost battalion". Bleckley entered service as a member of the Kansas National Guard, was commissioned as an artillery officer, then volunteered for aviation training and duty. His was one of the four Medals of Honor awarded to members of the Air Service in World War I.

The Lost Battalion is the name given to the nine companies of the US 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 the 194 remaining men were rescued. They were led by Major Charles W. Whittlesey. On 2 October, the 77th division launched an attack into the Argonne, under the belief that French forces were supporting their left flank and two American units including the 92nd Infantry Division were supporting their right. Within the 77th sector, some units, including Whittlesey's 308th Infantry, were making significant headway. Unknown to Whittlesey's unit, the units to their left and right had been stalled. Without this knowledge, the units that would become known as the Lost Battalion moved beyond the rest of the Allied line and found themselves surrounded by German forces. For the next six days, suffering heavy losses, the men of the Lost Battalion and the American units desperate to relieve them would fight an intense battle in the Argonne Forest.
