The first epidemic was sufficiently terrifying to cause some of the colonists to bolt their contract and attempt to return to the United States. When the smallpox broke out it proved to be too much for their sense of honor or any other restraining force. Those who were able began precipitously to desert the settlement for the United States, apparently giving no attention at all to the matter of sustenance for the journey. By the latter part of July all had left except about fifty of the most persistent and faithful who chose to stay by their crops.[11]
The sufferings of these colonists while at Tlahualilo and on their way to the Rio Grande furnished the press of the United States a sensational topic which it immediately seized upon. Indeed, the first report which reached the United States through official circles was itself sufficiently exaggerated to create excitement. On May 21, 1895, two fugitives from the colony arrived at Chihuahua City where they related stories of oppression and brutal cruelty. One of them reported that upon arriving at the colony the Negroes "found themselves in the worst form of bondage, with no hope of ever securing liberty," and that no letter informing friends of their condition and their suffering was ever permitted to reach the United States. He said he was one of a party of some fifty who had stolen away in the hope of making their escape. The other Negro declared that he was the sole survivor of a party of about forty which had likewise run away from the settlement, but had been overtaken and slain by a band of Mexican guards in the employment of the colonizing company. The consul of the United States at Chihuahua sent immediate notice of the affair to the State Department.[12]
E. C. Butler, chargé of the United States in Mexico, was immediately notified and directed to call upon the Mexican government to investigate the affair.[13] Meantime the consular officers of the United States began an investigation of their own which tended to convince them that the extravagant rumors regarding the cruelties perpetrated against the Negroes were totally unfounded. On June 24, the consul at Piedras Negras, Jesse W. Sparks, forwarded a report which he respectfully suggested should be given to the public "in order to contradict the terrible stories of murder and bad treatment of these Negroes ... and deter other Negroes who contemplate colonizing in Mexico." It was based upon a sworn statement made by the purported leader of the runaways, a deposition of another of the colonists, and information received through a traveller from New York City, who claimed to have visited the colony, as well as through a civil engineer who was in the employment of the Mexican International Railroad. From the information furnished by these witnesses Sparks drew the conclusion that the Mexican colonization company had lived up to its contract, that the Negroes had not been cruelly treated while at the colony, and that the report concerning the murder of a portion of the band[14] attempting to escape was absolutely false. The Mexican soldiers alleged to have slain the Negroes were in fact a relief party sent out by the company which, being acquainted with the barren and desolate nature of the country which would have to be crossed in reaching the United States, surmised that the lives of the colonists were in danger.[15]
