and Concord near Boston in April 1775, the colonies went to war. Washington appeared at the Second Continental Congress in a military uniform, signaling that he was prepared for war. Congress created the Continental Army on June 14, 1775, and discussed who should lead it. Washington had the prestige, military experience, charisma and military bearing of a military leader and was known as a strong patriot; he was also popular in his home province. There was no other serious competition for the post, although Washington did nothing to actively pursue the appointment. Massachusetts delegate John Adams nominated Washington, believing that appointing a southerner to lead what was then primarily an army of northerners would help unite the colonies. Washington reluctantly accepted, declaring "with the utmost sincerity, I do not think myself equal to the Command I [am] honored with." Washington assumed command of the colonial forces outside Boston on July 3, 1775, during the ongoing siege of Boston, after stopping in New York City to begin organizing military companies for its defense. His first steps were to establish procedures and to weld what had begun as militia regiments into an effective fighting force. He was assisted in this effort by his adjutant, Brigadier General Horatio Gates, and Major General Charles Lee, both of whom had significant experience serving in the British Army. When inventory returns exposed a dangerous shortage of gunpowder, Washington asked for new sources. British arsenals were raided (including some in the West Indies) and some manufacturing was attempted; a barely adequate supply (about 2.5 million pounds) was obtained by the end of 1776, mostly from France. In search of heavy weapons, he sent Henry Knox on an expedition to Fort Ticonderoga to retrieve cannons that had been captured there. He resisted repeated calls from Congress to launch attacks against the British in Boston, calling war councils that supported the decisions against such action. Before the Continental Navy was established in November 1775 he, without Congressional authorization, began arming a "secret navy" to prey on poorly protected British transports and supply ships. When Congress authorized an invasion of Quebec, believing that province's people would also rise against British military control, Washington reluctantly went along with it, even authorizing Benedict Arnold to lead a force from Cambridge to Quebec City through the wilderness of present-day Maine. As the siege dragged on, the matter of expiring enlistments became a matter
