In late July, the 100th Infantry Division participated in the Seventh Army's Operation TALLY-HO, a meticulous sweep of the entire zone of occupation in southwest Germany designed to discover contraband and root out wanted war criminals and German ex-soldiers still at large.

Individual rotations home after V-E Day were governed by a points system. Each soldier was awarded points based on total time in service, time overseas, decorations and badges, etc., all of which counted for a fixed number of points by Army policy. Soldiers with particularly high point totals began being rotated stateside throughout the summer, but the vast majority of Centurymen were far from the totals required for rotation when the tempo of tactical training increased in early August in anticipation of action in the Pacific.

On 10 August -- the day after the US Army Air Force detonated the second atomic bomb, in this case, over Nagasaki -- the Division was officially alerted for redeployment to the Pacific Theater of Operations. Ostensibly for commitment as a follow-on force for Operation CORONET, the invasion of the Japanese main island of Honshu in March, 1946, the exact employment of the Division fortunately never known, thanks to the decision of the Japanese emperor to surrender. On 18 August, the Division was officially stood down from its redeployment alert.

Company M. 397th Infantry receives the "Combat Infantry Company" streamer. Unit and individual awards were presented as they were approved throughout the spring and summer, but the personnel composition of the units continued to change.

Operation TALLY-HO netted contraband weapons, black market goods, and Nazi propaganda.
