Washington initially protested enlistment of slaves in the Continental Army, but later he relented when the British emancipated and used theirs. On January 16, 1776, Congress allowed free blacks to serve in the militia. By the end of the war one-tenth of Washington's army were blacks.
The Continental Army, further diminished by expiring short-term enlistments, and by January 1776 reduced by half to 9,600 men, had to be supplemented with militia, and was joined by Knox with heavy artillery captured from Fort Ticonderoga.
In March 1776, Abigail Adams, the wife and closest advisor of John Adams, second president of the U.S., saw an opportunity in the language of natural rights, and wrote to her husband, John Adams: In the new Code of Laws which I suppose it will be necessary for you to make I desire you would Remember the Ladies, and be more generous and favorable to them than your ancestors. Do not put such unlimited power into the hands of the Husband. Remember all Men would be tyrants if they could.
On March 17, 9,000 British troops and Loyalists began a chaotic ten-day evacuation of Boston aboard 120 ships. Soon after, Washington entered the city with 500 men, with explicit orders not to plunder the city. He ordered vaccinations against smallpox to great effect, as he did later in Morristown, New Jersey.
Washington then proceeded to New York City, arriving on April 13, 1776, and began constructing fortifications there to thwart the expected British attack. He ordered his occupying forces to treat civilians and their property with respect, to avoid the abuse suffered by civilians in Boston at the hands of British troops.
At the time of the Declaration of Independence in July 1776, the Continental Congress would not legally adopt flags with "stars, white in a blue field" for another year. The flag contemporaneously known as "the Continental Colors" has historically been referred to as the first national flag.
Siegmund Haffner, approached them with a request for music for his sister’s wedding, Mozart happily obliged. Hard as we might imagine today, the resulting Haffner Serenade was planned to be played at Marie Elisabeth Haffner 's wedding on July 21, 1776 for talking, cooking, drinking guests. Once again, the Haffner Serenade is one of Mozart 's early achievements — a brilliant work, full of complexity and imagination, despite receiving little attention from the audience at its first performance.
The Continental Navy raised the Colors as the ensign of the fledgling nation in the American War for Independence—likely with the expedient of transforming their previous British red ensigns by adding white stripes—and would use this flag until 1777, when it would form the basis for the subsequent de jure designs.
Howe's troop strength totaled 32,000 regulars and Hessians, and Washington's consisted of 23,000, mostly raw recruits and militia. In August, Howe landed 20,000 troops at Gravesend, Brooklyn, and approached Washington's fortifications, as King George III proclaimed the rebellious American colonists to be traitors.
Howe's pursuit forced Washington to retreat across the Hudson River to Fort Lee to avoid encirclement. Howe landed his troops on Manhattan in November and captured Fort Washington, inflicting high casualties on the Americans. Washington was responsible for delaying the retreat, though he blamed Congress and General Greene. Loyalists in New York considered Howe a liberator and spread a rumor that Washington had set fire to the city. Patriot morale reached its lowest when Lee was captured.
Washington crossed the Delaware River at sunset on Christmas Day, December 25, 1776, and risked capture staking out the Jersey shoreline. His men followed across the ice-obstructed river in sleet and snow at McKonkey's Ferry, with 40 men per vessel. Wind churned up the waters, and they were pelted with hail, but by 3:00 a.m. they made it across with no losses.
