The mining-casemate at Nahant, from which the mine-fields in Broad Sound, Boston Harbor, were to have been controlled, was placed in charge of Captain Bordman, who arrived with his command ("A" Battery) at this station on June 6th, and at once laid out his camp near the work to be guarded. Rapid-fire field guns were issued to this post, but infantry guard duty was practically all that was required of its garrison. Lieutenant Fullerton served as post adjutant until ordered to Fort Columbus, New York Harbor, on July 18th, where he remained on detached service until the muster-out of the regiment. The quartermaster and commissary duties were performed by Lieutenant Sumner Paine. Lacking the material for artillery work, Captain Bordman turned to infantry drill, and by constant road marches and field exercises brought his command into prime physical condition. The tour of the battery at this station was not destined to be a long one. In the rush of emergency harbor-work during the early days of the war, the Engineers first gave their attention to the mining of the main ship channel and Nantasket Roads, leaving Broad Sound—the water area for bombardment of Boston, Lynn, and Chelsea—for later consideration; but with the destruction of Cervera's fleet, all active mining operations came abruptly to a close, and the Broad Sound system remained uninstalled. The post at Nahant, therefore, was ordered to be abandoned on July 25th, its garrison reporting at Fort Pickering on that date. FORT RODMAN AND ITS GARRISON XII. THE second of the three general divisions into which the regiment had been separated—Lieutenant-Colonel Woodman's command, "G" (Chick's) and "L" (Whiting's) Batteries—arrived at its destination at New Bedford on June 1st, reporting to Lieutenant-Colonel Haskin, Second United States Artillery, commanding officer at Fort Adams, R.I. The post to be garrisoned was then borne on the army register as the "Fort at Clark's Point," the designation by which it had been known since 1857, when ground first was broken for its construction. The fort is an excellent type of the clever military engineering for which this country was noted at the middle of the century. It is an enclosed work of granite, with two tiers of casemate guns and provisions for a third tier in barbette, though the guns of the latter battery never have been mounted. In June last its armament was made up of 8- and 10-inch Rodmans, 100-pounder (6.4-inch) Parrott rifles, and 24-pounder (5.8-inch) flank-casemate howitzers. All through the summer and fall months the Engineers were steadily at work on exterior emplacements for 8-inch breech-loading rifles, on disappearing mounts, while mortar and rapid-fire batteries also were projected for the post; but during its occupation by its volunteer garrison the only available ordnance was that of the types of the Civil War.
