Red Redoubt. Battery Numbers 4, ten 13-inch motars, Moore's plateau. Battery No 5, four 20-pounder Parrotts, near Warwick road.

N. B.-Six 20-pounders were put in this battery.

Batteries Nos. 1 and 2 were immediately commenced and finished (essentially finished) in three days. Numbers 3 was commenced, but its construction was retarded by circumstances unnecessary to explain. The sites of Nos. 4 and 5 were not definitely fixed until two or three days later, and another, Battery Numbers 6, for six 4 1/2-inch ordnance rifled guns, was determined upon. Portions of parallel connecting Nos. 2 and 3, and from the left of Yorktown road to Numbers 5, were commenced in the edge of the woods by daylight on the 25th. The same night a parallel was run through the open ground from Numbers 3 to connect with those portions just mentioned, and carried to a depth of 4 feet and a width of 6 feet, affording good cover. The same night a portion of parallel was commenced from near the point marked on the map as Redoubt C to near the head of the ravine toward the York River, and carried to dimensions to afford cover.

On the night of the 27th a parallel was run across from the head of ravine in one night to the York River (or rather to the edge of bluff) and on the night of the 29th a branch or boyau was run from this to a point 200 yards more advanced on the bluff, from which the whole area between us and the fortress was seen, the gorge of the first redoubt taken in reverse, and the Red Redoubt plunged into.

I have not time to enter into the details of works and batteries, but will simply state that Battery Numbers 6 was changed into a battery for five sea-coast mortars, Battery Numbers 5 enlarged to contain eight 20-pounders, and Battery Numbers 3 enlarged to contain seven 20-pounder Parrotts. Batteries 7 and 8, for six 20-pounder Parrotts each, were built to operate on the work at Wynn's Mill; Battery Numbers 9, for ten 10-inch siege mortars; battery Numbers 10, for three 100-pounder Parrotts and seven 4 1/2-inch ordnance; Battery Numbers 11, for five 10-inch sea-coast mortars; Battery Numbers 12, for five 10-inch and five 8-inch siege mortars; Battery Numbers 13, for three 30-pounder Parrotts and four 30-pounder Parrotts, directed at the redoubt at Yorktown works and on to batteries capable of being used on Gloucester; Battery Numbers 14 for three 100-pounder Parrotts and one 100-pounder James, to operate on Yorktown water batteries and Gloucester. Another 200-pounder Parrott was ordered to Battery Numbers 1.

Redoubts A and B, for strengthening our line, were finished, Redoubt C well advanced, and Redoubt D just commenced on the night of May 3. A parallel had been run from Redoubt A to Battery Numbers 5, obstructions and portions of parallel from Redoubt A to Batteries 7 and 8. The foregoing applies to the state of the works on May 3; not to the particular time at which they were finished. A battery for two 8-inch siege howitzers was being commenced in a clearing south of the Wynn's Mill works, to enfilade that position, and two 8-inch mortars were to be put in position to operate on the works in front of General Smith's position.

On the night of May 3 all the batteries were armed (i. e., contained their armament) except three 100-pounders in Numbers 10, seven Parrott guns in Numbers 13, four 100-pounders in Numbers 14, and part of the sea-coast and siege 10 and 8 inch mortars were yet to be placed in battery.

All would have been ready on the night of the 5th, and the fire would have been opened on Tuesday morning. The water batteries would have been enfiladed by Batteries Nos. 1, 13, and 14, while they were in the direct line to receive all the shots of Numbers 10, which passed over the front of the work, and indeed Numbers 2 as well. The gunboats would have
