The strange fact is that many people these days take German claims for gospel truth is made even stranger by the fact that skepticism was much more rampant 75 years ago.

To put the German claims in perspective, Soviet forces in Kerch numbered 249,800 men at their peak. According to Isayev's research, their actual losses in the spring fighting were 162,282 men, 4,646 guns and mortars, and 196 tanks. It's highly unlikely that the stragglers that continued fighting after the collapse of the front managed to dig up thousands of tanks out of thin air. If these kind of claims aren't "greatly inflated", then I am greatly looking forward to seeing what the British thought was excessive overclaim.
