412 Nort Carorina Troops, 1861~’65. the Engineer Department a minute and complete map of the whole territory, from the Rapidan southward. This was ex- ecuted with the transit, and the main lines chained. Indeed the engineers advanced across the Rappahannock, to the line of the Occoquan and near Alexandria, and were pursued by naval and marine forces on the Potomac. But a fairly good map was obtained of the roads, redoubts, ete., constructed by the enemy beyond the river, When General Grant began his assaults by the left flank toward Richmond in 1864, every foot of ground had been studied by Lee, and the troops shifted with masterly pre- cision, met every attack by the shortest route, and on the ex- act spot required. Grant sacrificed as many men as equaled Lee’s entire army. It was perceived by the War Department at Richmond that the gathering of skilled men to supervise labor, and to exe- cute the details under the direction of officers temporarily or- dered for the erection or strengthening of works at various points, only to be seattered at the completion, and brought to- gether with difficulty at some other point, was a wasteful pro- cess, only permissible as a temporary expedient. In addition, therefore, to the Engineer Corps, it was de- termined to organize two regiments of Engineer Troops, of ten companies each. The officers were appointed by the President, and the nucleus of each company was to be ob- tained by detailing fifty men from each division or two men from each regiment, as far as possible from the same State, within a given district. The companies were to be organ- ized as a body of regulars. Commanding officers were re- quested to select only skilled men of approved record, in knowledge and conduct. The ranks were filled by volunteers reaching military age, or otherwise, to a minimum of one hundred men. Two new men were allowed in lieu of one veteran. As it was anticipated that these regiments would constitute a part of the regular army of the Confederate States, after the attainment of independence, and the disso- lution of the provisional army, the appointments were much appreciated, of commissions therein. Military graduates and military assistant engineers, then Corps oF ENGINEERS. 413 in service, and a few officers of the corps proper and staff of- ficers in other departments who resigned higher rank, to enter the permanent Engineer Troops, were made the commis- sioned officers of the line. All appointments were made as in the case of regulars. No elections were permitted. Com- missioned officers were selected by presidential appointment. From the nature of the service, the company was the unit, and the Captain appointed the non-commissioned officers. The First Regiment was assigned to the Army of Northern Virginia. The Second Regiment belonged to the South and West, along the Atlantic coast, and in the Army of the West. Company A of this regiment was formed chiefly of North Carolinians and assigned to North Carolina. In addition to the details from regiments in Lee’s army of North Caro- lina troops, the ranks were filled by enlistments at Wilming- ton. ; Congress authorized these regiments 20 March, 1863. General Lee at first opposed the removal of the companies from their several divisions to regimental headquarters, and in fact, the second regiment served in separate companies ghout the war. ee deletes of North Carolina in 1861 consisted of the forts Macon and Caswell, the former built for the defence of Beaufort, by the United States, and the latter, at the a of the Cape Fear, and the improvised earthworks constructe by the companies of heavy artillery volunteers, under the class of officers heretofore referred to. Several officers were commissioned by the State for this special duty, as S. L. Fremont, Colonel of Artillery and Engineers ; Major J. Hedrick, Major Jas. D.
