 TF Bengal consisted of soldiers and officers of the infantry, field artillery, and engineer units from the 256th Brigade as well as the 1st Battalion, 69th Infantry (The Fighting 69th) from New York City which had been attached for the deployment.Attached to the 69th Infantry was Delta 101, a company of tankers and scouts turned infantrymen from New York's 101st Cavalry Regiment.During the American Civil War, the 69th engaged the ancestral units of the 256th many times, so their attachment to each other for OIF provided a symbolic reconciliation 140 years after they fought each other to the death repeatedly from 1861 to 1865.
