representatives of Belize and Guatemala were on high alert; Yucatan refugees fled into both Guatemala and Belize and even the Belize superintendent came to fear that Carrera – given his strong alliance with Guatemalan natives – could support the native uprisings in Central America. In the 1850s, the British showed their good will to settle the territorial differences with the Central American countries: they withdrew from the Mosquito Coast in Nicaragua and began talks that would end up in the restoration of the territory to Nicaragua in 1894: returned the Bay Islands to Honduras and even negotiated with the American filibuster William Walker in an effort to avoid the invasion of Honduras. They also signed a treaty with Guatemala about its border with Belize, which has been called by Guatemalans the worst mistake made by the conservative regime of Rafael Carrera. Aycinena y Piñol, as Foreign Secretary, had made an extra effort to keep good relations with the British crown. In 1859, William Walker's threat loomed again over Central America; in order to get the weapons needed to face the filibuster, Carrera's regime had to come to terms about Belize with the British Empire. On 30 April 1859, the Wyke-Aycinena treaty was signed between the English and Guatemalan representatives. The controversial Wyke-Aycinena from 1859 had two parts: The first six articles clearly defined the Guatemala-Belize border: Guatemala acknowledged England sovereignty over the Belize territory. The seventh article was about the construction of a road between Belize City and Guatemala City, which would be of mutual benefit, as Belize needed a way to communicate with the Pacific coast of Guatemala, having lost its commercial relevance after the construction of the transoceanic railroad in Panama in 1855; on the other hand, Guatemala needed a road to improve communication with its Atlantic coast. However, the road was never built; first because Guatemalan and Belizeans could not reach an agreement of the exact location for the road, and later because the conservatives lost power in Guatemala in 1871, and the liberal government declared the treaty void. Among those who signed the treaty was José Milla y Vidaurre, who worked with Aycinena in the Foreign Ministry. Rafael Carrera ratified the treaty on 1 May 1859, while Charles Lennox Wyke, British consul in Guatemala, traveled to Great Britain and received the royal approval on 26 September 1859. There were some protests coming from the U.S. consul,
