1st District of Columbia Cavalry
Eight companies for this regiment were organized at Augusta, Me., from Oct. 1863, to March, 1864, to serve three years, and assigned as Companies D, F, G, H, I, K, L and M. This regiment was originally designed for special service in the District of Columbia, and was under the command of Col. L. C. Baker.
After performing important service in and about Washington for several months, half of the regiment was ordered to Portsmouth, Va., and dismounted; the other half was assigned to Gen. Butlerís command, and participated in Gen. Kautz cavalry raid in the early part of June, 1864.
On the 23d of August, the regiment had an engagement with the Hampton Legion; also participated the next day in the action near Reamsí Station.
All the Maine officers and enlisted men were transferred to the 1st Me.l Cavalry, Aug 25th, but did not then join the latter regiment, and remained doing picket duty on the extreme left of the army, on a line about four miles in length.
On the 15th of Sept. the regiment was attacked by a large force of the enemy, and after a gallant resistance was compelled to retreat, losing heavily in killed and a large number being taken prisoners. The remaining men then joined the 1st Me. Cavalry, and from this date the history of the regiment is identical with that of the 1st Me. Cavalry.
