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.
