Later in the same month, the Earl of Dartmouth, then a member of the British Cabinet, wrote from London to Col. Johnson, that it was the King's pleasure "That you lose no time in taking such steps as may induce the Indians to take up the hatchet against his Majesty's rebellious subjects in America." This letter was accompanied by a large assortment of presents for the Indians, and Col. Johnson was urged not to fail to use "the utmost diligence and activity" in accomplishing the purpose. Col. Johnson was joined in Canada in the spring of the following year by his brother-in-law, Sir John Johnson, the son and heir of Sir William. Sir John had organized a force known as the Royal Greens, composed of loyalists from the New York frontier, and mainly former tenants and dependents of his father's estate. The Mohawks, who alone of all the Six Nations had gone to Canada, were slow to yield to the importunities of the English, in so far as taking an active part in the war was concerned. A topic of far deeper interest to them was their title to certain lands in the Mohawk and upper Susquehanna Valleys, concerning which they had failed to secure adjustments for many years. In November, 1775, Joseph Brant with other Indian chiefs, sailed for England with a view to accomplishing a settlement of this dispute. An interview took place with the Colonial Secretary, who subsequently was in direct charge of the war in America, Lord George Germaine. Brant made two speeches before Germaine, outlining the grievances of his people, and it is clear from one of them that Germaine then secured the adhesion of Brant to the English cause by promising to redress the Indian grievances after the war, and to keep for the Indians the favor and protection of the King. Thenceforth the responsibility for Indian activity in the Revolution rests mainly on Germaine. It was to him that Lord Chatham referred in a memorable speech on the American War: "But, my lord, who is the man, that, in addition to the disgrace and mischiefs of the war, has dared to authorize and associate to our arms the tomahawk and scalping knife of the savage? To call into civilized alliance the wild and inhuman inhabitants of the woods? To delegate to the merciless Indian the defense of disputed right, and to wage the horrors of his barbarous war against our brethren? My lords, these enormities cry aloud for redress and punishment."
