Some historians have viewed Grant as a "butcher" commander who in 1864 used attrition without regard to the lives of his own soldiers in order to kill off the enemy which could no longer replenish its losses.Throughout the Civil War Grant's armies incurred approximately 154,000 casualties, while having inflicted 191,000 casualties on his opposing Confederate armies.In terms of success, Grant was the only general during the Civil War who received the surrender of three Confederate armies. Although Grant maintained high casualties during the Overland Campaign in 1864, his aggressive fighting strategy was in compliance with the U.S. government's strategic war aims. Grant has recently been praised by historians for his "military genius", and viewed as a decisive general who emphasized movement and logistics.
