Immediately on the first driven in to the Jamestown and Edenton roads. Immediately on the first alarm the long roll was beaten, and the troops deployed in line along the breastworks, running right and left from Fort Dix. Third relative conditions continued as follows until the siege was raised: The Sixty-ninth Regiment defending works in front of its camp, on the right of the line; the One hundred and sixty-fourth Regiment next in line and first on the left of the said fort; the One hundred and fifty-fifth at first marched up from their camp in reserve and formed along the works, bivouacking at night between the One hundred and sixty-fourth and One hundred and Seventieth Regiments, and on the left of the One hundred and sixty-fourth.

April 15.-No action was taken offensively on the part of this Legion against the enemy until the 15th instant, when a small force was sent out on the Edenton road to reconnoiter., This force consisted of one company from the One hundred and fifty-fifth Regiment (Company I), one company from the One hundred and seventieth, and company from the One hundred and sixty-fourth (Company C), together with a squadron of cavalry from the First New Mounted Rifles, and one 6-pounder,the whole force under the command of Colonel McMahon, of the One hundred and sixty-fourth Regiment, Major Patton having charge of the cavalry and gun. it started from Fort Dix at 2.30 a. m., and, after marching 2 1/2 miles out on the Edenton road, drove in the enemy's mounted pickets, follows them as rapidly as possible to - Mill, where they found a rebel regiment drawn up in line of battle to receive them. The enemy were posted in the rear of a large field, on the right of the road covering a cross-road, which led across the mill-dam to the Somertom road. Here a conflict ensued of half an hour's duration, when the enemy retreated, taking up his second position on the opposite side of the mill-pound. A few well-directed shots from the 6-pounder gun drove him from this place, where re-enforcements arrived to the enemy. Colonel McMahon, after advising with Major Patton, deemed it best to retire, the object of the reconnaissance being accomplished the entire camp equipage of the enemy captured, besides some provisions and 3 prisoners.
