[1] The 107th Infantry Division initially served on the Eastern Front, seeing its first action in the Battle of Lemberg (now Lviv) and later participating in the capture of Brest-Litovsk and of Pinsk.
After a brief respite on the Macedonian front, the division went back to Russia at the beginning of January 1916.
In November 1917, the division was sent to the Western Front, entering the line in the German "Siegfried" position.
The division moved to the St. Mihiel salient in September and then occupied the line in the Woëvre region.
Cavalry was reduced, artillery and signals commands were formed, and combat engineer support was expanded to a full pioneer battalion.
