I'd certainly give 'Death Traps' by Belton Cooper a check. The book follows the advance of the 3rd Armored Division, from their humble beginnings at the shore of England and all through their journey as Operation Spearhead. It's essentially Cooper's memoirs of service as a leading member of the mechanic and recovery team. The stories within paint a very grim reality of the tragic war and tell of many brave and, questionably stupid, soldiers as they fight the battles through the advance on German territory.
