Quotes
“He was not a brilliant soldier but a safe one, he never sacrificed his men for the mere sake of winning to himself the attention of newspaper correspondents and the plaudits of the public but whenever hard work was to be done or hard knocks to be received, he was ready. He was social in his habits; kind and considerate to officers and men; ever alive to their needs and comfort and always with them from the beginning to the end. He never received a furlough; his life was in camp with his men.” Ezra Carman
“General Williams handled the corps with judgment and firmness, and I felt entire confidence in leaving it under his charge.” Henry Slocum, who repeatedly left Williams in corps command, wrote approvingly of him after Gettysburg, OR 27, Pt. 1, pp. 758–770
“His predecessor, General A. S. Williams, the senior division commander present, had commanded the corps well from Atlanta to Goldsboro, and it may have seemed unjust to replace him at that precise moment…” William T. Sherman, Memoirs of General William T. Sherman, Vol. II, Chapter on Carolinas Campaign
George Gordon characterized Williams as calm, methodical, and unemotional in command, a general who inspired confidence rather than excitement in his book, Brook Farm to Cedar Mountain (1883).
“I seem destined to command when others are disabled, and to be forgotten when promotions are made.” Alpheus Williams, From the Cannon’s Mouth: The Civil War Letters of General Alpheus S. Williams
“I have no taste for intrigue, and therefore little chance for advancement.” Alpheus Williams, From the Cannon’s Mouth: The Civil War Letters of General Alpheus S. Williams
“I do my work quietly and as well as I can, but I do not make myself conspicuous.” Alpheus Williams, From the Cannon’s Mouth, p. 198
McClellan left little explicit commentary on Alpheus Williams, but his actions speak clearly. When Mansfield was mortally wounded at Antietam, McClellan allowed Williams to assume and retain command of the XII Corps without interference or subsequent criticism—an implicit endorsement from a commander otherwise known for distrust of subordinates
