I've read Jordan but not Tucker as well. I find it amazing that we have had no less than three (maybe four?) bios of George Thomas come out in the last little bit here but we do not have hardly anything on Hancock, who played a large role in the war in the East until his Gettysburg wound forced him out of active duty in late 1864. I assume since Hancock never became an army commander Thomas has a large advantage in terms of being suitable material for a biographer. One of my side projects has been to start collecting bios of Union and Confederate army, corps, and division commanders who served during the Siege of Petersburg, so I for one would welcome a new Hancock biography.
