I'm sure I posted this a while back, but I'm damned if I can find it. Anyway, 78 British, 85 German, 1 American, 5 Turkish, dozens of Russian and 444 French generals were killed, according to this old thread on AHF. http://forum.axishistory.com/viewtopic.php?f=72&t=55900
Bloody Red Tabs has the stoies of some 250+ british general officer casualties. http://books.google.co.uk/books/about/Bloody_Red_Tabs.html?id=_eRmAAAAMAAJ .
Yes, great book, I have it in my collection. Always a good one to shoot down the usual "no-generals-got-killed-in-that-war" idiots.
