But before the Green Mountain Boys reached Ticonderoga, Arnold joined them to assume command of their force. As Ethan Allen refused to give it up, the two patriots headed the force together. They came upon the fort so unexpectedly that, at the cry of "Surrender!" the British commander sprang out of bed and rushed to the door, defiantly asking, "By what authority?" "In the name of the great Jehovah and the Continental Congress!" thundered Ethan Allen. The British officer was forced to yield, although he knew the Green Mountain Boys could have no such orders, for the Second Continental Congress was to assemble only the next day. The taking of Ticonderoga, and of Crown Point on the morrow, proved a great help to the Revolutionary cause, for the patriots thus secured, cannon and powder which they were to need before long. Traveling rapidly from place to place, the news of the battle of Lexington soon spread all through the colonies. The congressional delegates, therefore, left their homes to meet in Philadelphia, knowing there was a great piece of work before them. One of them, George Washington, felt it so keenly that before starting he wrote to his brother: "It is my full intention to devote my life and fortune to the cause we are engaged in, if needful." It was well that he was so ready to serve his country, for it was sorely in need of help. Congress no sooner assembled, with Hancock for president, than it began to govern the country, and called for an army of fifteen thousand men. Adams then arose, saying he would like to propose as general a gentleman from Virginia, whose "skill and experience as an officer, independent fortune, great talents, and universal character will command the approval of all America." George Washington, who had expected nothing of the sort, and who was as modest as he was good, fled from the room when he heard this. But every one voted for him, and when he was called back he reluctantly accepted the charge given him, saying: "I beg it may be remembered by every gentleman in this room that I this day declare, with the utmost sincerity, I do not think myself equal to the command I am honored with." But he then went on to say that he would do his best, and refused all pay for his services, asking only that Congress should pay his expenses, of which he would keep an exact account. Washington wrote to his wife, at Mount Vernon: "I should enjoy more real happiness in one month with you at home than I have the most distant prospect of finding abroad, if my stay were seven times seven years." But as he always did his duty promptly and cheerfully, he immediately set out on horseback for Boston, where the continental troops were rapidly assembling.
