Within the fortifications the colonists were in a miserable plight. They had little shelter, the rain fell in torrents, and a cold northeast wind chilled them to the bone. They had nothing to eat except dry biscuit and raw pork. They were hungry and weary, wet and cold. Yet one of their miseries was a blessing. For as long as the northeast wind blew Howe could not bring his ships up the East River and cut communications between Long Island and New York. For in those days, it must be remembered, there were no steamers, and sailing vessels had to depend on wind and tide. Washington, however, knew his danger. He knew that he must withdraw from Long Island. So secretly he gave orders that everything which could be found in the shape of a boat was to be brought to Brooklyn Ferry. They were soon gathered, and at eight o'clock in the evening, two days after the battle of Long Island, quickly and quietly the army was ferried across the wide river to the New York side. All night the rowers laboured, but the work was by no means finished when day dawned. The weather, however, still helped the colonists, for a thick fog settled over the river and hid what was going on from the British. Wounded, prisoners, cannon, stores, horses, were all ferried over, and when later in the day the British marched into the deserted camp they found not so much as a crust of bread. It was about six in the morning when the last boat put off, and in it was Washington, the last man to leave. For forty hours he had hardly been off his horse, and had never for a minute lain down to rest. He was unwearyingly watchful, and left nothing to chance, and this retreat is looked upon as one of the most masterly in all military history. Having abandoned Brooklyn Washington knew that he could not hope to hold New York against an attack. But for a fortnight neither Admiral nor General Howe made any attack. Instead they talked once more of peace. It almost seemed as if Lord Howe were on the side of the Americans, as indeed he had always said he was, until he was ordered out to fight against them. "He is either a very slow officer, or else he is our very good friend," said one of them. The fortnight which he now wasted gave Washington time to decide what it was best to do, and when at last the British began the attack on New York nearly all the stores and cannon had already been removed to Harlem Heights, about ten miles away at the north of Manhattan Island. All the troops, too, had gone except about four thousand under General Putnam, who stayed to keep order, and look after the removal of the last of the stores. When the attack came these were very nearly caught. For the regiment who ought to have guarded the landing place, and have kept the enemy from advancing until Putnam could retire, ran away as soon as they saw the red coats.
