These new developments and the new domestic problems which they involved all tended to divert public thought from the old political issues arising out of the war. Foreign relations, too, began to take on a new interest. The Alabama claims controversy with England continued to hold the public attention until finally settled by the Geneva Arbitration in 1872. President Grant, as much of an expansionist as Seward, for two years (1869-71) tried to secure Santo Domingo or a part of it for an American naval base in the West Indies. But the United States had race problems enough already and the Senate, led by Sumner, refused to sanction the acquisition. Relations with Spain were frequently strained on account of American filibustering expeditions to aid Cuban insurgents. Spain repeatedly charged the United States with laxness toward such violations of international law; and President Grant, seeing no other way out, recommended in 1869 and again in 1870 that the Cuban insurgents be recognized as belligerents, but still the Senate held back. The climax came in 1873, when the Spanish authorities in Cuba captured on the high seas the Virginius* with a filibustering expedition on board and executed fifty-three of the crew and passengers, among them eight Americans. For a time war seemed imminent, but Spain acted quickly and effected a peaceable settlement.
