All that night the daring band of blue-jackets held the fort unmolested. But on the following morning the townspeople again plucked up courage, and to the number of five hundred marched to the fort, and placing several pieces of artillery in battery, summoned the garrison to surrender. The flag of truce that bore the summons carried also the threat, that, unless the Americans laid down their arms without resistance, the fort would be stormed, and all therein put to the sword without mercy. For answer to the summons, the Americans nailed their colors to the mast, and swore that while a man of them lived the fort should not be surrendered. By this bold defiance they so awed the enemy that the day passed without the expected assault; and at night the besiegers returned to their homes, without having fired a shot. All that night the Americans worked busily, transferring to the "Providence" all the ammunition and stores in the fort; and the next morning the prizes were manned, the guns of the fort spiked, and the adventurous Yankees set sail in triumph. For three days they had held possession of the island, though outnumbered tenfold by the inhabitants; they had captured large quantities of ammunition and naval stores; they had freed their captured countrymen; they had retaken from the British five captured American vessels, and in the whole affair they had lost not a single man. It was an achievement of which a force of triple the number might have been proud. In February, 1778, the Delaware, along the water-front of Philadelphia, was the scene of some dashing work by American sailors, under the command of Capt. John Barry. This officer was in command of the "Effingham," one of the vessels which had been trapped in the Delaware by the unexpected occupation of Philadelphia by the British. The inactivity of the vessels, which had taken refuge at Whitehall, was a sore disappointment to Barry, who longed for the excitement and dangers of actual battle. With the British in force at Philadelphia, it was madness to think of taking the frigates down the stream. But Barry rightly thought that what could not be done with a heavy ship might be done with a few light boats. Philadelphia was then crowded with British troops. The soldiers were well provided with money, and, finding themselves quartered in a city for the winter, led a life of continual gayety. The great accession to the population of the town made it necessary to draw upon the country far and near for provisions; and boats were continually plying upon the Delaware, carrying provisions to the city. To intercept some of these boats, and to give the merry British officers a taste of starvation, was Barry's plan.
