The "right moment" came at last. In a single night the soldiers fortified Dorchester Heights, cannonading the enemy's batteries in the opposite direction, so that their attention was diverted from the real work. When the morning dawned of March 5, 1776, General Howe saw, through the lifting fog, the new fortress, with the guns turned upon Boston. "I know not what to do," he said. "The rebels have done more work in one night than my whole army would have done in one month." He resolved to attack the "rebels" by night, and for this attack twenty-five hundred men were embarked in boats. But a violent storm set in, and they could not land. The next day the rain poured in torrents, and when the second night came Dorchester Heights were too strong to be attacked. The proud General Howe was compelled to evacuate Boston with all possible dispatch, March 17, the navy going to Halifax and the army to New York. The Americans at once occupied the city, and planted the flag above the forts. Congress moved a vote of thanks to Washington, and ordered a gold medal, bearing his face, as the deliverer of Boston from British rule. The English considered this a humiliating defeat. The Duke of Manchester, in the House of Lords, said: "British generals, whose name never met with a blot of dishonor, are forced to quit that town, which was the first object of the war, the immediate cause of hostilities, the place of arms, which has cost this nation more than a million to defend." The Continental Army soon repaired to New York. Washington spared no pains to keep a high moral standard among his men. He said, in one of his orders: "The general is sorry to be informed that the foolish and wicked practice of profane cursing and swearing--a vice heretofore little known in an American army--is growing into fashion. He hopes the officers will, by example as well as influence, endeavor to check it, and that both they and the men will reflect that we can have little hope of the blessing of Heaven on our arms if we insult it by our impiety and folly. Added to this, it is a vice so mean and low, without any temptation, that every man of sense and character detests and despises it." Noble words! Great Britain now realized that the fight must be in earnest, and hired twenty thousand Hessians to help subjugate the colonies. When Admiral Howe came over from England, he tried to talk about peace with "Mr." Washington, or "George Washington, Esq.," as it was deemed beneath his dignity to acknowledge that the "rebels" had a general. The Americans could not talk about peace, with such treatment. Soon the first desperate battle was fought, on Long Island, August 27, 1776, partly on the ground now occupied by Greenwood Cemetery, between eight thousand Americans and more than twice their number of trained Hessians. Washington, from an eminence, watched the terrible conflict, wringing his hands, and exclaiming, "What brave fellows I must this day lose!"
