The agent in this transaction was Orville E. Babcock, a young officer figuring in the Blue Book of the time as one of the unauthorized “secretaries” at the Executive Mansion, and also as a major of engineers. His published instructions, under date of July 13, 1869, were simply to make inquiries; but the plot appears in a communication of the same date from the Secretary of the Navy, directed to the Seminole, a war-ship, with an armament of one eleven-inch gun and four thirty-two pounders, “to give him the _moral support_ of its guns”; and this was followed by a telegraphic instruction to Key West for another war-ship “to proceed without a moment’s delay to San Domingo City, to be placed at the disposal of General Babcock while on that coast.”[149] With such “moral support” the emissary of the President obtained from the usurper Baez that famous Protocol stipulating the annexion of Dominica to the United States in consideration of $1,500,000, which the young officer, fresh from the Executive Mansion, professed to execute as “Aide-de-Camp to his Excellency General Ulysses S. Grant, President of the United States,”--as if, instead of Chief Magistrate of a Republic, the President were a military chieftain with his foot in the stirrup, surrounded by a military staff. The same instrument contained the unblushing stipulation, that “his Excellency General Grant, President of the United States, promises, _privately, to use all his influence_, in order that the idea of annexing the Dominican Republic to the United States may acquire such a degree of popularity among members of Congress as will be necessary for its accomplishment”:[150] which is simply that the President shall become a lobbyist to bring about the annexion by Congress. Such was the strange beginning, illegal, unconstitutional, and offensive in every particular, but showing the Presidential character. On his return to Washington, the young officer, who had assumed to be “Aide-de-Camp to his Excellency General Ulysses S. Grant,” and had bound the President to become a lobbyist for a wretched scheme, instead of being disowned and reprimanded, was sent back to the usurper with instructions to negotiate two treaties,--one for the annexion of the half-island of Dominica, and the other for the lease of the Bay of Samana.[151] By the Constitution of the United States “ambassadors and other public ministers” are appointed by the President by and with the advice and consent of the Senate; but our Aide-de-Camp had no such commission. Presidential prerogative empowered him. Nor was naval force wanting. With three war-ships at his disposal,[152] he concluded negotiations with Baez and obtained the two treaties. Naturally force was needed to keep the usurper in power while he sold his country, and naturally such a transaction required a Presidential Aide-de-Camp unknown to Constitution or Law, rather than a civilian duly appointed according to both.
