Puerto Cabezas
On 9 April 1961, Brigade 2506 personnel, ships, and aircraft started transferring from Guatemala to Puerto Cabezas. Curtiss C-46s were also used for transport between Retalhuleu and a CIA base (code-named "JMTide", aka "Happy Valley") at Puerto Cabezas. Facilities and limited logistical assistance were provided by the governments of General Miguel Ydígoras Fuentes in Guatemala, and General Luis Somoza Debayle in Nicaragua, but no military personnel or equipment of those nations was directly employed in the conflict. Both governments later received military training and equipment, including some of the CIA's remaining B-26s.
