The siege lasted until the evening of the 8th of April, when Spanish Fort surrendered. Up to the last the enemy sent down torpedoes, and that night eighteen were taken from Blakely River. Commander Pierce Crosby, of the Metacomet, at once began sweeping above, and so successfully that on the 10th the Octorara and ironclads were able to move abreast Spanish Fort and shell two earthworks, called Huger and Tracy, some distance above. These were abandoned on the evening of the 11th, when the fleet took possession. Commander Crosby again went on with the work of lifting torpedoes, removing in all over one hundred and fifty. The way being thus cleared, on the 12th Commander Palmer with the Octorara and ironclads moved up the Blakely to the point where it branches off from the Tensaw, and down the latter stream, coming out about a mile from Mobile, within easy shelling distance. At the same time Admiral Thatcher, with the gunboats and 8,000 troops under General Granger, crossed the head of the bay to attack the city, which was immediately given up; the Confederate troops having already withdrawn. The vessels of the enemy, which had taken little part in the defence, had gone up the Tombigbee.
The navy at once began to remove the obstructions in the main ship channel and lift the torpedoes, which were numerous. While doing the latter duty, two tugs, the Ida and Althea, and a launch of the ironclad Cincinnati were blown up. By these accidents 8 were killed and 5 wounded. The gunboat Sciota was also sunk in the same manner on the 14th of April, the explosion breaking the spar deck beams and doing much other damage. Her loss was 6 killed and 5 wounded.
The rebellion was now breaking up. Lee had laid down his arms on the 9th, and Johnston on the 24th of April. On the 4th of May General Richard Taylor surrendered the army in the Department of Alabama and Mississippi to General Canby; and the same day Commodore Farrand delivered the vessels under his command in the waters of Alabama to Admiral Thatcher, the officers and crews being paroled. Sabine Pass and Galveston, which had never been retaken after their loss early in 1863, were given up on the 25th of May and the 2d of June.
In July, 1865, the East and West Gulf Squadrons were merged into one under Admiral Thatcher. Reasons of public policy caused this arrangement to continue until May, 1867, when the attempt of the French emperor to establish an imperial government in Mexico having been given up, the Gulf Squadron as a distinct organization ceased to be. Thus ended the last of the separate fleets which the Civil War had called into existence. The old cruising ground of the Home Squadron again became a single command under the name, which it still retains, of the North Atlantic Squadron.
