General David M. Gregg

David Gregg resigned his army commission, in a letter dated January 25, 1865: Having for more than three years been on uninterrupted service in the field, commanding cavalry in the Army of the Potomac, I at this time find such an imperative demand for my continued presence at home that my personal attention may be given to pressing private duties and business, that I can no longer defer action to secure my discharge from the service. Gregg's real reasons for resigning are unknown.
