from command), he surrendered the fort on August 8. Siege of Fort Morgan As soon as the surrender of Fort Gaines was completed, Granger moved his force from Dauphin Island to the narrow strip of mainland behind Fort Morgan, where they were landed without opposition about away, well out of range of its guns. The fort was thus immediately invested, cut off from all communication with Mobile. Granger set about taking the fort by regular approaches — that is, establishing a sequence of trenches or other protective lines drawn ever closer to the objective, until finally its walls could be breached and it could be taken by assault. His first line was a gift, a line of trenches from the fort that had been prepared by the garrison of the fort and then for some reason abandoned. It was a little farther than he would have liked, but it served quite well. Additional parallels were built with little interference, as the laborers could work behind the sand dunes. While this was going on, monitors Winnebago, Chickasaw, and Manhattan were engaging in occasional bombardment. They were later joined by the former CSS Tennessee, captured on August 5, since repaired, and now renamed USS Tennessee. The most serious hindrance to the advance in this period was the weather; a storm on August 20 halted work for a while, and left standing water in low places. The fort was subjected to a day-long bombardment on August 22 from 16 siege mortars, 18 guns of various sizes, and the fleet, the monitors and Tennessee at short range and the rest of the ships at long range. Inside the fort, Brig. Gen. Page feared that the bombardment would endanger his magazines, which contained of powder. To avoid the risk, he had the powder brought out and flooded. That night, the magazines were indeed threatened when the woodwork of the citadel caught fire. The fire brought an increase in the rate of bombardment, and was extinguished only with great effort. Feeling now that further resistance was useless, on August 23 Page ordered his remaining guns spiked or otherwise destroyed as far as possible. At 6 AM, he ordered the white flag raised, and the siege was over.
