General D. P. WOODBURY,

Commanding Engineer Brigade:

GENERAL: I have the honor to report that on Saturday, the 15th instant, at the time your order to move reached me, my command was distributed in the following manner: Companies C and K, under command of Captain Chester, were at Fort Albany, Va., superintending the works in that quarter; Company A, under Captain Bogan, guarding the Anacostia (upper) Bridge; Company D, the Navy-yard Bridge; Companies H and E were stationed near Fort Meigs, working on new fortifications, and Company G encamped near Fort Baker, building bridges.

At 12.30 o'clock on the 15th, I received your order to embark four companies. Not being willing to delay the transport, I at once dispatched Companies B, F, and I, which still remained in camp, and embarked them, with tools, from the Sixth street wharf, Washington, by 4 p.m. Meantime the scattered companies were ordered in and the men rations for a march.

On Sunday,at 5 p.m., I embarked with six companies of board the steamer Hero, leaving Company K to guard the wagon train, which, by order, was to come by land. Having started with a raft of forty-eight pontoon boats in tow, we steamed as far as the Arsenal, where, the water being shallow, we grounded, and could not get afloat until 5 p.m. Monday, from the impossibility of procuring a tug to pull the steamer off. We dropped down the Potomac as far as Fort Washington, when the captain, not venturing to proceed with so large a tow in the night, anchored.

By daylight of the 18th, we were under way, and at 3 p.m. anchored 3 miles from Belle Plain. As no other means of disembarking presented themselves, I moved the men onto the pontoon raft, and towed the flotilla to the shore.

On the morning of the 19th, agreeably to the order to assist the commissary and quartermaster, I laid a pier of pontoons for each, and commenced a more permanent pier for the commissary, besides assisting in
