Moody and the Columbia Detachment disbanded in July 1863 and Moody returned to England. Douglas continued to administer the mainland colony in absentia from Victoria, but Sir Arthur Kennedy was appointed to succeed him as Governor of Vancouver Island. New Westminster would welcome its first "resident" governor, Frederick Seymour, in 1864. Both colonies were labouring under huge debts, largely accumulated by the completion of extensive infrastructure to service the huge population influx. As gold revenues dropped, the loans secured to pay for these projects undermined the economies of the colonies, and pressure grew in London for their amalgamation. Despite a great deal of ambivalence in some quarters, on 6 August 1866, the united colony was proclaimed, with the capital and assembly in Victoria, and Seymour was designated governor.
