=172. Slow Growth of the Idea of Independence.=--We must not fail to remember that the idea of independence took form very slowly. The first "Stamp Act," so offensive to the colonists, became a law in 1764, more than ten years before actual hostilities broke out. During all those years our ancestors were gradually losing their friendly feeling for England. They were slowly drifting towards an open conflict, in fact, the Revolution. This hostility to England grew to be a serious matter after the battle of Bunker Hill. It was deepened and embittered early in 1776 by a number of events that still more sharply estranged America from her unkind mother. After the battle the British continued to occupy Boston with many hostile demonstrations, just as if it were an enemy's country, until at the end of a long siege they were driven out by Washington. This weary investment caused a great deal of bitterness. Everything took on the sombre shadow of war, and this of course meant permanent hostility to England. Another step that greatly angered the Americans, and very justly too, was a British proclamation, the design and effect of which was to destroy all the commerce of the colonies by forfeiting their ships. This was itself equal to a declaration of war by England. Then three petitions to the king, George III, by three different congresses, were treated with indifference or even with insolent contempt. The only obvious effect of the petitions was to goad England to greater severities. To a proposal at one time to exchange prisoners, it was answered that England "received no applications from rebels, unless they came to implore the king's mercy." This stinging and insolent reply necessarily implied that all American patriots were rebels; that they were guilty of treason; that, but for the king's mercy, they must expect the penalty of treason, which is death! =173. Active Measures taken by the British.=--Meanwhile obstinate King George, humored by his prime minister, Lord North, was busily making enormous preparations for pushing the war upon a large scale. Already twenty-five thousand British soldiers had been sent to America, or had been enlisted for immediate service. But so large a party in England was opposed to the war against their own countrymen in the colonies, that the king could not raise at home all the troops he needed. So he made a bargain with a German state, Hesse, hiring twenty thousand foreign soldiers to cross the ocean and fight his rebellious subjects.

But even worse still, it was learned that the British government was taking steps, by means of secret agents, to employ the Indians to fight on the British side, and use their tomahawks against British colonists!
