COH2 reading list
From a Brit perspective, I can recommend:
With the Jocks - Peter White - but it is a long book.
18 Platoon - Sydney Jary (recommended reading for Sandhurst cadets, apparently)
So few got through - With the Gordon Highlanders from Normandy to the Baltic - Martin Lindsay. Originally published in 1946, and reprinted in 2012. The story of a battalion 2 i.c., who was often commanding the battalion in attack, when his COs were away. This book apparently became mandatory British Army Staff College reading,
Lindsay presents as a highly competent officer. What the book does not say is that Lindsay was a Lt Colonel i.c. 9 Para, until March 1944. 9 Para led the assault on the Merville Battery on 06 June 1944. For more about that, you would have to read The manner of men: 9 PARA's Heroic D-Day Mission
