On September 24, the squadron again relocated, this time to Remicourt, aerodrome of the I Corps Observation Group.
On September 26, 1918, supporting the 77th Division, the 50th Aero Squadron flew its first missions of the Meuse-Argonne Offensive with a complement of 15 pilots, 15 observers, and 16 Liberties.
At the beginning of October, units of the 308th Infantry Regiment were cut off and surrounded by German troops.
Able to communicate with division headquarters only by carrier pigeon, the battalion-sized force inadvertently supplied division headquarters with incorrect coordinates of its location.
As early as October 2 the 50th Aero Squadron searched for signs of the cut-off battalion, and on October 5, the division commander, Maj.
Gen. Robert Alexander, requested that the 50th Aero Squadron locate and resupply the "Lost Battalion" by air with ammunition, rations, and medical supplies.
Four attempts to pinpoint the location were unsuccessful in increasingly bad weather.

On October 6, the 50th flew 13 additional missions, ultimately having three aircraft shot down, in what the USAF has termed the first combat airlift in history.
In addition to supplies, the 50th attempted to drop two baskets of carrier pigeons to the 308th, using small parachutes from flares to soften the descent.
The first resupply mission, flown by Lt.s Floyd M. Pickrell and Alfred C. George, took off shortly before noon in poor visibility.
The DH-4 of Lt.s Maurice F. Graham and James E. McCurdy returned from the last mission with McCurdy seriously wounded by a bullet through the neck, but also with confirmation that the location given by the lost battalion was incorrect and occupied by German forces.
