So instead of submitting they made ready to fight. The British also prepared to fight, and the force of the next blow fell upon New York. There were now more than thirty thousand British troops gathered here. It was the largest army which had ever been sent out of England, and King George had never a doubt that this great force, backed by his unconquerable navy, would soon bring the ten or twenty thousand ragged, half starved rebels to their knees. He little knew the men or the man which who he had to deal. The army was indeed ragged and undisciplined. But as the great Napoleon said later, "In war the man is everything." And Washington was soon to show the world what could be done by brave undisciplined men whose hearts were behind their muskets. As soon as Washington had gained possession of Boston he left an old general with a small force to guard it, and transported the main body of his army to New York, feeling sure that the next attack would be made there. Brooklyn Heights on Long Island commanded New York, very much in the same way as Bunker Hill and Dorchester Heights commanded Boston, and Washington knew he must keep possession of those heights, if New York was not to be given up without a blow being struck. He did not want to give it up without striking a blow, for he feared the effect on the spirits of the country. So he send General Putnam with about eight thousand men to occupy the Heights. In doing this Washington placed his army in a very dangerous position, for the East River was large enough to allow British war ships to sail up it and thus cut his army in two. But he could do nothing else, for if the enemy got possession of the Heights the town was at his mercy. Howe was not slow to see this, and, having carefully and secretly made his plans, he attacked the forces on Brooklyn Heights in the early morning of August 27th in front, and flank, and rear, all at once. One division of the Americans was nearly wiped out, many being killed and the rest being taken prisoner. A little band of Marylanders put up a fine but hopeless fight for nearly four hours, the remnant of them at length taking refuge in the fortifications. To make the defeat a disaster for the colonists Howe had but to storm these fortifications. But he refused to do so. Enough had been done for one day, he said. Bunker Hill had taught the British to beware of storming heights. A siege would be less costly, thought Howe.
