1917 Redux?
The Russian army is crumbling. Russian forces are surrendering in Kherson. This means that a large contingent, over 10, O00 Russian troops, are now going into captivity.
This is a happy logistics problem. Go into a POW camp, and get sleep for the first time in months. Get a warm meal, medical care, and maybe clean clothes. Give them books, and chess sets, to keep busy, and let them call home and write letters home.
