First day, to sunset Early on the morning of 28 August, ,
USS Wabash, and
USS Cumberland began to bombard Fort Clark, while the lighter warships accompanied the transports to a point about to the east, where the troops began disembarking. Stringham kept his ships moving in a loop, with
Wabash towing
Cumberland. About 11:00 a.m.,
USS Susquehanna "made her number" and joined in. The ships would deliver their broadsides against the fort, move back out of range to reload, and then come back in to fire again. By remaining in motion, they did not let the artillerymen in the fort correct their aim between shots, and thereby negated much of the traditional advantage of shore-based guns over those on ships. This tactic had been used previously by the British and French at the
siege of Sevastopol in the
Crimean War, but this was the first time it was used by the US Navy. The return fire from Fort Clark was ineffectual, either falling short or passing overhead, and no hits were made on the bombarding ships. Shortly after noon, the defenders ran low on ammunition, and about 12:25 p.m. they ran out completely. At this point, they abandoned the fort, some fleeing to Fort Hatteras, while others took to boats. Col.
Max Weber, commanding the Federal troops already on shore, noted this and put some men in to take possession, but the fleet did not know this and continued firing for another five minutes. It was during this interval of confusion that the landing force suffered its only casualty, one of the soldiers being seriously wounded in the hand by a shell fragment. Fortunately, some of the troops were able to get the attention of the gunners on the ships by waving a large American flag, and the bombardment stopped with no further harm done. Stringham and his captains then turned their attention to Fort Hatteras. Meanwhile, the landings were not going well. Only about a third of the troops were ashore when rising winds produced surf that swamped and overturned the landing boats, and General Butler had to suspend further attempts to land. Colonel Weber found that he had only 318 men with him. The number included 102 from his own regiment, the 20th New York, but also 68 from the 9th New York, 28 from the Union Coast Guard, 45 artillerymen, 45
marines, and 28 sailors who could man heavy guns. With several field pieces that they had managed to wrestle ashore through the surf, they could reasonably well defend themselves against a Confederate counterattack, but they were too weak to mount an attack on Fort Hatteras. As the day came to a close, the fleet drew off in the face of threatening weather, the exhausted defenders looked for reinforcements, and the Federal troops ashore went to sleep supperless, with water running low, and dreading the reinforcements that their opponents hoped for.
After sunset, and second day Sometime after dark, reinforcements began to arrive at the fort. The gunboat
CSS Warren Winslow brought in some of the garrison from Fort Ocracoke, and some of the sailors also stayed to help man the guns. This brought the number of men in the fort up to more than 700, with more expected from New Bern. Accompanying the additional troops was Flag Officer
Samuel Barron, commanding the coast defenses of North Carolina and Virginia. Colonel Martin, pleading exhaustion, requested Barron to assume command. He did so, still believing that with the additional troops from New Bern they would be able to retake Fort Clark. Dawn of the second day blasted the hopes of the defenders. The weather moderated enough that the Union fleet could return and resume its bombardment; they were also able to drive off the transport bringing reinforcements. (Somehow a ship was able to get in, but rather than bringing in more troops she carried away some of the wounded.) The fleet initially kept in motion, but they soon found that they were out of range of the guns in the fort. After that, the ships did not alter their positions, but poured their fire into the fort with no danger of reply. There was nothing the men in the forts could do except endure. After about three hours, Barron called a council of the officers, and they decided to seek terms, even though casualties had been quite light. (The actual numbers of dead and wounded are known only very imprecisely. Various reports give the number of dead as from four to seven, and the wounded as from 20 to 45) At a little after 11:00 a.m., the white flag was shown. Butler insisted upon surrender, which Barron agreed to. The battle came to a close, and the survivors went into prisoner-of-war camps. The list of prisoners had 691 names, including those wounded but not evacuated. ==Aftermath==
