About George Brinton McClellan

1864 presidential election

Currier and Ives print of the McClellan–Pendleton Democratic presidential party ticket, 1864. Lithograph with watercolor. Secretary Stanton ordered McClellan to report to Trenton, New Jersey, for further orders, although none were issued. As the war progressed, there were various calls to return McClellan to an important command, following the Union defeats at Fredericksburg and Chancellorsville, as Robert E. Lee moved north at the start of the Gettysburg campaign, and as Jubal Early threatened Washington in 1864. When Ulysses S. Grant became general-in-chief, he discussed returning McClellan to an unspecified position. But all of these opportunities were impossible, given the opposition within the administration and the knowledge that McClellan posed a potential political threat. McClellan worked for months on a lengthy report describing his two major campaigns and his successes in organizing the Army, replying to his critics and justifying his actions by accusing the administration of undercutting him and denying him necessary reinforcements. The War Department was reluctant to publish his report because, just after completing it in October 1863, McClellan openly declared his entrance to the political stage as a Democrat. However, the debate over McClellan's ability and talents remains the subject of much controversy among Civil War and military historians. He has been universally praised for his organizational abilities and for his very good relations with his troops. Other nicknames McClellan received included "Young Napoleon" McClellan himself summed up his style of warfare in a draft of his memoirs:

It has always been my opinion that the true course in conducting military operations, is to make no movement until the preparations are as complete as circumstances permit, & never to fight a battle without some definite object worth the probable loss.
