In the book Ivan's War by Catherine Merridale on page 148 it states that in 1942:

"A hundred and seventy six thousand men were slaughtered at Kerch in just twelve days"

Is this true? Are any sources for this number?

What shocks me the most about this quote is not the amount of deaths but that they died in less than 2 weeks. That's an average of almost 14,700 men a day for twelve straight days.

Are there any other death tolls equal to or greater than the one at Kerch in a similar time frame on the Eastern Front?

I'm talking about individual battles not entire campaigns. What's the worst amount of Soviet casualties taken at a single battle or battles in a short time frame (no greater than a month) that occurred on the Eastern Front?
