quartermaster trains. The ammunition trains of the Artillery Reserve and artillery brigades attached to corps can be employed for the transport of the ammunition. There should be provided for each siege gun 1,000 rounds of ammunition; for each siege mortar 600 shells; for each Coehorn mortar 200. Of this ammunition 200 rounds per piece should be brought up before opening fire; the remainder to be near enough to enable the supply to be kept up. At least 500 sand-bags should be supplied for each gun and mortar of the train, with an equal number in reserve. I would propose that the organization of the train be instructed to Colonel Abbot, First Connecticut Artillery, whose regiment served with the siege train at the siege of Yorktown. That the work may proceed with the utmost rapidity, another regiment of foot artillery (Kellogg's, Warner's, or Piper's) might be added to Colonel Abbot's command. Colonel Kellogg served with credit in the First Connecticut Artillery at Yorktown, and is familiar with the duties. The two regiments of foot artillery in the reserve will be available as reliefs, guards for working parties, fabrication of gabions and fascines, filling sand-bags, &c. The instruction of the regiments with the train in the mechanical maneuvers, laying of platforms, &c., should commence at once. A thorough knowledge of these duties will save much time when every hour is valuable. The material and working directions for constructing magazines, one for every four guns, should also be prepared in advance, that workmen drawn from the foot artillery regiments with the army may assist the engineers or construct them themselves. It is understood that there are rifled 32-pounders, 4-inch caliber, in the works at Richmond. Should it be considered necessary to oppose to them guns of corresponding power (100-pounders) the ordnance officer should be instructed to prepare them and their material. This would be a timely precaution. In case it should be thought necessary to move the train by water up the Pamunkey to the neighborhood of Hanover Court-House, instructions should be given to load the material on barges, double-decked ones if possible, such as are used on the Hudson River for transportation of flour, and do not draw more than five feet. This depth I understand is found as far up as the bridge at Widow Lumkin's, near Crump Creek, and within five miles by land of the railroad. The depth of water and the nature of the road from the bridge to the railway should be ascertained positively before procuring the barges. A decked scow or two and 100 or 200 feet of trestle bridging, similar to that prepared by Major Duane for the pontoon train, but of stronger dimensions, should be provided to enable landings to be effected at any point.
Respectfully, your obedient servant,
HENRY J. HUNT,
Brigadier-General and Chief of Artillery.
