On the arrival of the fleet it was decided to attack and capture Charleston, and overthrow the new government there. General Charles Lee was sent down by Congress to defend the city, but the South Carolina patriots proved quite able to take care of themselves. On Sullivan's Island in Charleston harbour Colonel William Moultrie built a low elastic fortress of palmetto logs supported by banks of sand and mounting several heavy guns. In the cannonade which took place on the 28th of June this rude structure escaped with little injury, while its guns inflicted such serious damage upon the fleet that the British were obliged to abandon for the present all thought of taking Charleston. In the course of July they sailed for New York harbour to reinforce General Howe. On the 12th of that month the general's brother, Richard, Lord Howe, arrived at Staten Island to take the chief command of the fleet. He was one of the ablest seamen of his time, and was a favourite with his sailors, by whom, on account of his swarthy complexion, he was familiarly known as "Black Dick." Lord Howe and his brother were authorized to offer terms to the Americans and endeavour to restore peace by negotiation. It was not easy, however, to find any one in America with whom to negotiate. Lord Howe was sincerely desirous of making peace and doing something to heal the troubles which had brought on the war; and he seems to have supposed that some good might be effected by private interviews with leading Americans. To send a message to Congress was, of course, not to be thought of; for that would be equivalent to recognizing Congress as a body entitled to speak for the American people. He brought with him an assurance of amnesty and pardon for all such rebels as would lay down their arms, and decided that it would be best to send it to the American commander; but as it was not proper to recognize the military rank which had been conferred upon Washington by a revolutionary body, he addressed his message to "George Washington, Esq.," as to a private citizen. When Washington refused to receive such a message, his lordship could think of no one else to approach except the royal governors. But they had all fled, except Governor Franklin of New Jersey, who was under close confinement in East Windsor, Connecticut. All British authority in the United States had disappeared, and there was no one for Lord Howe to negotiate with, unless he should bethink himself of some way of laying his case before Congress.
