Even erroneous reports of desertion could prevent a disabled veteran, or his dependents from receiving a pension. I've seen cases in which a man was once reported deserted while he was in hospital from combat wounds. He returned to duty, was later wounded again, and discharged as disabled. But, the desertion record had not been expunged , and it took him two years, and an Act of Congress for him to get a pension! In another case, a sick woman and three children were denied a pension and left destitute because her husband had deserted.
Most deserters, of course, simply disappeared and were never heard from again. Moved away, or taking a new name, no one knew they were deserters.
