Formed in France in July 1918, the group was assigned to the 1st Pursuit Wing and saw action in the final months of the war, supporting the Battle of Saint-Mihiel and the Meuse-Argonne Offensive.

The next day, the squadrons pressed home similar attacks as well as flying advanced reconnaissance patrols near the Mad River and in the region between Conflans-sur-Seine, Mare la Tour and Chambley.

[1] After the Saint-Mihiel attacks, the group settled down to a routine schedule of defensive patrols over the line, carrying out bombing raids when weather permitted.

On 20/21 September the group moved to the Lisle-en-Barrois Aerodrome, closer to the front; however, its patrols remained flying their previous sector, not to betray the planning for the upcoming offensive.

The squadrons engaged in constant sorties, bombing and machine gunning enemy forces in front of the infantry troops attacking.

[1] Throughout the entire campaign the group carried out bombing raids and strafing of infantry to harass and disrupt the enemy's retreat, and these continued until the end of hostilities.

Although hampered by a heavy ground mist, low clouds and intermittent rain, 930 kg of bombs were dropped on various enemy targets on the very last day of the war.
