POWs

According to the hand writing, the men fled after being captured by the french. I suppose the PG-stamping marks them as prisoners? Anyway they could use some new clothes. The card is dated September 20th, 1917

I have been wondering about the headgear of the guy in the middle.

Anything to keep the head warm.

PG = Prisonnier de guerre / Prisoner of War.
