The following thread http://www.ww2incolor.com/forum/showthread.php/15538-MacArthur-vs-Patton-Who-was-the-better-general?p=197393#post197393 on whether Patton or MacArthur was the better commander led me to think about less well known generals who, like Patton, weren’t conventional types or who did remarkable things and, often, weren’t adequately rewarded or recognised or even sidelined or virtually punished for their success. And who, had their talents been better utilised, might have had a useful effect on their side’s war.
This thread isn’t limited to Allied generals / commanders.
Here are two to get the discussion going.
Yamashita did brilliantly with a relatively modest force in Malaya, having declined a larger force because he correctly thought the logistics weren’t sustainable. Despite his victory he was sidelined by Tojo for most of the war in Manchukuo and was only brought out into serious combat against the Allies when he was given a losing hand towards the end of 1944 in the Philippines.
Terry Allen, who served under Patton in North Africa, was probably much more of a cavalryman but much less a poseur than Patton when one looks at Allen’s cavalry work in military and civilian aspects before WWII. Allen’s 1st Infantry Division (Big Red One) did reasonably well in North Africa while in Sicily in 1943 his unusual training focusing on night attacks possibly saved the Allies from being repulsed on their beachhead. He was relieved of command when winning later at an important point at Troina in the Sicily campaign, then sent back to the US where he trained the 104th Infantry Division which under his command in Europe went on to do well from Normandy to Germany.
