My understanding while hazy is that assorted pockets of Germans in the East experienced very hard doses of brutality in the first couple of weeks of May.
German forces in Czechoslovakia were still fighting to escape the Soviets as late as May 13. What they were fighting with, I don’t know. They certainly ceased receiving any meaningful supplies in late April, so they must have been fighting with whatever they had on hand.
You know they were desperately trying to escape to the west to surrender to the Americans.
