Kock also proposed a scheme to certain capitalists in New York and Boston. This had nothing to do with the contract with the President. He proposed to transport 500 of these emigrants at once, begin work on the plantations, and by the end of the following September--a period of eight or nine months--he estimated that this group could raise a crop of 1,000 bales of cotton. It was planned that the colonists should secure from the island a profit of more than 600 per cent in nine months. Kock estimated his necessary expenses as $70,000, and all expense incurred by freighting ships and collecting immigrants was to be borne by the government. It soon became known to the government that Kock had sought the aid of capitalists and money makers. Suspicion as to the honesty of his purposes was then aroused. It was finally discovered also that he was in league with certain confederates to hand over slaves to him as captured runaways on the condition of receiving a price for their return. Lincoln investigated the matter and discovered that Kock was a mere adventurer and the agreement with him was cancelled.[27] A certain group of capitalists, whose names are not mentioned, then secured the lease from Kock and entered into contract with the government through the Secretary of the Interior, April 6, 1863.[28] Under this agreement a shipload of colonists from the contrabands at Fortress Monroe, said to number 411-435, were embarked.[29] An infectious disease broke out through the presence on board of patients from the military hospital on Craney Island and from twenty to thirty died. On the arrival in the colony no hospitals were ready, no houses were provided, and the resulting conditions were appalling. Kock was sent along as Governor, and he is said to have put on the air of a despot and by his neglect of the sick and needy to have made himself obnoxious. Rumors of the situation came to the President and he sent a special agent, D. C. Donnohue, who investigated the matter and made a report. Donnohue elaborately described the deplorable situation of the inhabitants, the wretched condition of the small houses and the prevalence of sickness. He further reported that the Haytian government was unwilling that emigrants should remain upon the island and that the emigrants themselves desired to return to the United States. Acting upon the report, the President ordered the Secretary of War to dispatch a vessel to bring home the colonists desiring to return.[30] On the fourth of March the vessel set sail and landed at the Potomac River opposite Alexandria on the twentieth of the same month. On the twelfth of March, 1864, a report was submitted to the Senate showing what portion of the appropriation for colonization had been expended and the several steps which had been taken for the execution of the acts of Congress.[31] On July 2, 1864, Congress repealed its appropriation and no further effort was made at colonization.[32]
