Secretary of War John B. Floyd, onetime governor of Virginia and a strong secessionist sympathizer, condemned Anderson’s occupation of Fort Sumter and urged President Buchanan not to send reinforcements.

Anderson thought he had “tangible evidence” of hostile intent, both towards Fort Moultrie—an old fort vulnerable to land attack—and toward Fort Sumter, then occupied by about 80 engineer workmen. He moved, Anderson afterwards wrote to Secretary of War John B. Floyd, “to prevent the effusion of blood” and because he was certain “that if attacked my men must have been sacrificed, and the command of the harbor lost.” To Anderson, a Kentuckian married to a Georgian, preservation of peace was of paramount importance. At the same time, as a veteran soldier of unquestioned loyalty, he had a duty to perform.

Charlestonians were outraged. Crowds collected in the streets; military organizations paraded; and “loud and violent were the expressions of feeling against Major Anderson and his action.” On December 27 South Carolina volunteers occupied Fort Moultrie and Castle Pinckney, a third harbor fort, and began erecting defensive batteries elsewhere around the harbor. South Carolina’s governor, Francis Pickens, regarded Anderson’s move not only as an “outrageous breach of faith” but an act of aggression, and demanded, through commissioners sent to Washington, that the Federal Government evacuate Charleston Harbor. On December 28 President Buchanan, while admitting that the occupation of Sumter was against his policy, refused to accede to the demand.

The North was exultant. On New Year’s Day, 1861, amid cheers for Major Anderson, salvos of artillery resounded in northern cities. By an imposing majority, the House of Representatives voted approval of Anderson’s “bold and patriotic” act. The only question that remained was whether the national government would continue to support him.

At Fort Sumter, Anderson’s 85 officers and men (plus the engineer workmen who remained after the fort was occupied) garrisoned a fortification intended for as many as 650 and had “about 4 months” supply of provisions. In January President Buchanan was persuaded to send off a relief expedition. Initial plans called for sending the sloop of war Brooklyn for this purpose, but when word arrived that the South Carolinians had obstructed the harbor entrance by sinking several ships, it was decided to use the Star of the West, an ordinary merchant ship, which would excite less suspicion and avoid the appearance of coercive intent. Two hundred men, small arms and ammunition, and several months’ provisions were placed aboard. The men were to remain below deck on entering Charleston Harbor; the Brooklyn would follow, in case the Star of the West were fired upon and disabled.

But Charleston had been forewarned, and when the Star of the West appeared at the entrance of the harbor on January 9, 1861, cadets from the Citadel military college opened fire with several cannons mounted on Morris Island. The unarmed ship turned back. Anderson had held his fire, thinking the firing unauthorized. Orders authorizing supporting fire on his part had failed to reach him in time. For the moment, civil war had been avoided.

Further relief plans were now shelved, since President Buchanan was anxious to end his term of office in peace. Yet it was apparent that eventually the garrison would have to be supplied or the fort abandoned.

On January 10, Acting Secretary of War Joseph Holt (Floyd, a Southern sympathizer, had resigned over Buchanan’s refusal to evacuate Fort Sumter) ordered Anderson to act strictly on the defensive. Anderson and Governor Pickens had already exchanged angry letters over the firing on the Star of the West, and when the major refused the governor’s demand to surrender the fort (January 11), Pickens sent Isaac W. Haynes, the State’s attorney general, to Washington to try once again to get the Federal troops removed. If this failed, Haynes was to offer to buy the fort from the government. President Buchanan refused to do either. The stalemate continued.
