You mean the German younger generations’ “guilty conscience reminder”?
exactly. It is okay to remember and learn from history, but he’s going far beyond… just my humble opinion.
Stalingrad was in Autumn/winter 42/43. Heeresgruppe Mitte was defeated in winter 41 near Moscow by “General Winter” and fresh troops coming
from East. But I think you’re right about winter gear. They hesitated too long and didn’t have enough transport capacity then. But in such conditions I wouldn’t think of winter overcoats as niceties…
