What was the Soviet reaction to the División Azul (blue division) on the Eastern front in WWII?

Hi Indie and team.

I was wondering what the Soviet reaction was to the Blue División of Spanish volunteers on the Eastern Front. Were they aware if its presence and were they in any way angered by such large numbers from what was technically a neutral country fighting against it?


Excellent question, thnx. I also wonder as they also represented the fascists from the civil war
