Alfred Pleasonton was born July 7, 1824 in the District of Columbia. As Acting Adjutant General for the Department of Oregon, Pleasonton wrote almost all orders to Capt. George Pickett and Lt. Col. Silas Casey during the Pig War crisis.
Unfortunately for Pleasonton, he was not in the orbit of the newly coined U.S. Army commander, Lt. Gen. Ulysses S. Grant. As a result, on March 25, 1864, he was replaced as head of the Army of the Union cavalry corps by Philip Sheridan. Transferred to the Department of the Missouri, Pleasonton's cavalry performed ably in a campaign against Confederate Maj. Gen. Sterling Price. But while arguing with another Union general over who should receive credit for the victory, Price slipped away to fight another day.
The town of Pleasanton, CA is named for him.
