In July 1676 Andros established a haven for the Mahicans and other Indian war refugees at Schaghticoke. Although the conflict came to an end in southern New England in 1676, there continued to be friction between the Abenakis of northern New England and English settlers. These prompted Andros to send a force to the duke's territory in Maine, where they established a fort at Pemaquid (present-day Bristol). Andros annoyed Massachusetts fishermen by restricting their use of the duke's land for drying fish. In November 1677 Andros departed for England, where he would spend the next year. During this visit he was knighted as a reward for his performance as governor, and he sat in on meetings of the Lords of Trade in which agents for Massachusetts Bay defended its charter, and gave detailed accounts of the state of his colony. The southernmost territories of the duke, roughly encompassing northern Delaware, were desired by Charles Calvert, Baron Baltimore, who sought to extend the reach of his proprietary Province of Maryland into the area. At the same time Calvert was seeking an end to a frontier war with the Iroquois to the north, having persuaded the intervening Susquehannocks to move to the Potomac River, well within Maryland territory. Furthermore, the Lenape, who dominated Delaware Bay, were unhappy with seizures of their lands by Virginia and Maryland settlers, and war between these groups had been imminent in 1673 when the Dutch retook New York. When Andros came to New York, he moved to stabilize the situation. He befriended the Lenape sachems (chiefs), convincing them to act as mediators between the English and other tribes. Peace appeared to be imminent when Bacon's Rebellion broke out in Virginia, resulting in an attack on the Susquehannock fort on the Potomac. The surviving Susquehannocks sneaked out of the fort one night, some of them making their way east toward Delaware Bay. In June 1676 Andros offered, in exchange for their moving into his jurisdiction, to protect them from their enemies among the Virginian and Maryland settlers. He also extended an offer given by the Mohawk for the Susquehannocks to settle among them. These offers were well received, but Maryland authorities were unable to convince their Indian allies to make the peace offered by Andros, and organized them to march toward the Delaware, which would also fulfil the goal of strengthening the Maryland claim to the area. Andros responded by urging the Susquehannocks to retreat into New York, where they would be beyond Maryland's reach, and delivering a strongly worded threat to Maryland, that it would either have to acknowledge his sovereignty over the Susquehannocks, or they would have to peaceably take them back.
