BH Liddell Hart's tomes on WWII. Brilliant books. Although he clearly was a little "too sympathetic" to the German cause.
It's true, he sounds too enthusiastic with the German operations and very sympathetic to some Nazi officers (Rommel and Manstein for example), but I think it stems from his overall enthusiasm with strategy and military operations in general.
While for most people a dead soldier is still a horribly murdered human, I think his view is that battles between armies do not count as atrocities (not an uncommon view) and officers who didn't murder civilians (or allege they didn't know civilians were murdered under their command) should not be tried for war crimes. Of course that's a bit too much to swallow, especially on the soviet side.
By the way, the same argument was applied for scientists as well (see Wernher von Braun and the operation paperclip bunch, who also "didn't know")
