This time line is drawn largely from the work of Richard B. Morris, in particular his Encyclopedia of American History.
"Common Sense." Thomas Paine moved many to the cause of independence with his pamphlet titled "Common Sense." In a direct, simple style, he cried out against King George III and the monarchical form of government.
The British Evacuate Boston. American General Henry Knox arrived in Boston with cannons he had moved with great difficulty from Fort Ticonderoga, New York. Americans began to entrench themselves around Boston, planning to attack the British. British General William Howe planned an attack, but eventually retreated from Boston.
Congress Calls for the Colonies to Adopt New Constitutions. In May, the Second Continental Congress recommended that the colonies establish new governments based on the authority of the people of the respective colonies rather than on the British Crown.
Congress Declares Independence. When North Carolina and Virginia empowered their delegates to vote for American independence, Virginian Richard Henry Lee offered a resolution stating that the colonies "are, and of right ought to be, free and independent States." A committee was appointed to draft a declaration of independence, and Thomas Jefferson was chosen to write it. On July 2, Congress voted in favor of independence, and on July 4, the Declaration of Independence was approved. Copies were sent throughout the colonies to be read publicly.
Battle of Long Island. After leaving Boston, British General Howe planned to use New York as a base. The British captured Staten Island and began a military build-up on Long Island in preparation for an advance on Brooklyn. Washington succeeded in saving his army by secretly retreating onto Manhattan Island. Washington eventually retreated from Manhattan, fearing the prospect of being trapped on the island, and the British occupied New York City.
Congress Names Commissioners to Treat with Foreign Nations. Congress sent a delegation of three men to Europe -- Silas Deane, Benjamin Franklin, and Arthur Lee -- to prepare treaties of commerce and friendship, and to attempt to secure loans from foreign nations.
The Battle of White Plains. British and American forces met at White Plains, New York, where the British captured an important fortification. Washington once again retreated, still attempting to save his army from the full force of the British army.
Retreat through New Jersey. Washington and his army retreated across New Jersey, crossing the Delaware River into Pennsylvania. Congress, fearing a British attack on Philadelphia, fled to Baltimore.
Battle of Trenton. On December 26, Washington launched a surprise attack against a British fortification at Trenton, New Jersey, that was staffed by Hessian soldiers. After one hour of confused fighting, the Hessians surrendered. Only five American soldiers were killed.
