Upon two occasions subsequently questions arose between the two governments involving the stipulations of the treaty. In 1888, and again in 1894, the United States felt called upon to protest against British interference in the affairs of the Mosquito coast.[178] The ground of interposition on the part of Great Britain was alleged to be found in the treaty of Managua, signed between Great Britain and Nicaragua on the 28th of January, 1860. This convention, it will be remembered, was one of the three treaties entered into by Great Britain with Central American republics with a view to removing the causes of dispute in the construction of the Clayton-Bulwer treaty. The treaty of Managua assigned a district to the Mosquito Indians within the limits of the republic of Nicaragua. The sovereignty of Nicaragua over the district was recognized, but the Indians were secured in the possession and enjoyment of their own domestic customs and regulations. It was agreed, however, that nothing in the treaty should prevent the Mosquitos at any subsequent date from voluntarily agreeing to absolute incorporation with the republic of Nicaragua. By the terms of the treaty the protectorate of Great Britain over the Mosquito coast was to cease three months after the exchange of ratifications. In reply to the protest of 1888, Lord Salisbury said that her majesty's government had no intention to assert a protectorate in substance or in form over the Mosquito nation, but that according to the convention with Nicaragua of 1860, Great Britain undertook "to secure certain rights and privileges to the Mosquito Indians, and in the event, which has arisen, of the Mosquito Indians complaining that their rights are infringed by Nicaragua, by whom is remonstrance to be made to Nicaragua unless by Great Britain, with whom she has concluded the convention in question?"[179] In the spring of 1894, yet more serious trouble arose. The Mosquito territory was invaded by the troops of Nicaragua and Bluefields was surrounded. The British consul at that point protested against this act as contrary to the treaty of Managua. The protest being unheeded, a force of troops was landed from the British ship _Cleopatra_ and on March 9, the Nicaraguans were forced to retire. Mr. Bayard was instructed by telegraph "to ascertain and report fully by cable the occasion for this action." The British government disavowed all intention of violating the Clayton-Bulwer treaty, which it recognized "as extant and in full force." In July, 1894, United States marines were landed at Bluefields to protect American interests and to restore order. Later the British government assured Mr. Bayard that its action had been wholly unconnected with any political or conventional question touching the Mosquito reservation, but simply to protect British interests.
