His only success was staking an American claim to uninhabited Wake Island in the Pacific, which would be officially claimed by the U.S. in 1898. He came close with the Danish West Indies as Denmark agreed to sell and the local population approved the transfer in a plebiscite, but the Senate never voted on the treaty and it expired.[180]
Another treaty that fared badly was the Johnson-Clarendon convention, negotiated in settlement of the Alabama Claims, for damages to American shipping from British-built Confederate raiders. Negotiated by the United States Minister to Britain, former Maryland senator Reverdy Johnson, in late 1868, it was ignored by the Senate during the remainder of the President's term. The treaty was rejected after he left office, and the Grant administration later negotiated considerably better terms from Britain.
