rear of General Sumner's headquarters. After remaining a few hours, the regiment advanced a few hundred yards.

On the morning of the 12th, we crossed the Rappahannock River on a pontoon bridge, under cover of our artillery, and encamped on the river bank. The regiment remained there during the night.

On the morning of the 13th, about 7 o'clock, we received orders to march to the battle-field. We moved with the brigade to support French's division. About 12 m. we entered the battle-field, holding a position on the extreme left of the brigade, directly opposite one of the enemy's batteries. After one hour's hard fighting, during which the regiment received orders to charge the enemy's works, which they did with the courage and bravery of veterans, they were withdrawn with the brigade from the field. The regiment then received orders from the commanding general to take the wounded and recross the river, and encamped for the night in the rear of General Sumner's headquarters.

On Sunday morning the remnant of the regiment again marched to Fredericksburg, with the expectation of again attacking the enemy. We remained in the town till Monday night, when the regiment, with the brigade,marched back to their old camps near Falmouth.

The officers and men behaved with great gallantry and coolness during the whole of the action.

Very respectfully, your obedient servant,

JOHN TEED,

Captain, Commanding Regiment.
