Brigadier General Lockwood and the command problem

Brigadier General Henry H. Lockwood commanded the brigade at the Battle of Gettysburg. Lockwood (West Point Class of 1836) was a professor at the United States Naval Academy. The brigade had just joined the Army of the Potomac from rear area duty in Maryland and presented a command dilemma.

Lockwood was senior to other brigadiers in the First Division and would properly have been given command of the division while Alpheus Williams temporarily commanded the corps. But Lockwood had never led troops in battle and had not even commanded his brigade as a unit on the field. So it was decided to have him report directly to the corps commander (Williams, at this point). This allowed the experienced Ruger to temporarily take over the division. For that reason the brigade is often referred to as “Lockwood’s Independent Brigade” at Gettysburg.

After the battle Slocum returned to corps command, Williams to his division. Lockwood had proved himself in battle. His brigade became the Second Brigade of the First Division on July 5th.
