Holland thentatement fromthe evidence implicating the Guatemalan and Costa RlcanIn the recent attack on Oeneral Soman,

stated that the total Information nowthe following conclusions:

a. The attack on Somoaa'a lifeenuine attempt mademall group of Nicaraguan exiles, mostly former members of the Caribbean Legion, including acquisition of arms, for this attempt (plueicaraguane recruited in Nicaragua by General Chamorro).

_ b. The conspirators were tolerated In Costa Rica but were mot demonstrably supported by the Costa Rlcan Their presence in Coata Rica waa tolerated by President Figuerea, who apparently had knowledge of their plana. The Nicaraguan Ambassador in Coata Rica was well Informedthe activities of the Nicaraguann that country, and reported hie information to the Costa Rican Government. Nothing waa dona by the Costa Rlcan Government to prevent the departure of thla group for the attack on Nicaragua.

Guatemalan Government waa notin tha preparation or execution of the plan.

involved in the plot or gave aid and comfort to the conaplratore.

He haa produced certain documentary evidence to support these

Mr, Leddyaccording report Figueres had gone even farther incomplicity to Ambassador Hill. said she had not

seen this report. Mr. Holland said he would ask the Ambassador tothe circumstances of this "admission."

Holland conceded, apart from the question of anyof complicity by President Figueres, that there seemed toevidence showingonspiratorial attack againstfriendly country had been mounted in Costa Rica, thatRican government had been warned that this action wae beingend had failed to take any positive action to restrain the attempt.

Leddy said that additional clrcumstanclal evidenceFigueres1 complicity was given in Ambassador Hill's reportsseeming "terror" that the extent of his connection with thcgroup would be revealed. Mr, Leddy explained that Figueres'

political prestige had been declining that/proof of his involvement might

result in an internal Costa Rica political criala.




he main Incidents of the assassination attempt madeware as follows:

A group ofen, mostly former members of the Caribbean Legion and mostlyith one Cuban and one Guatemalan among them, entered Nicaraguaoint near Granada from Coata Rica. They carried withiscellaneous collection of rifles, pistols, submachine guna, ammunition and grenadea.

They were aided In entering Nicaragua by Humberto Chamorro ana other members of the Chamorro family,

Most of tbe evidence bearing on this entire Incident, from the early rumors circulating In Coata Rica as early asown to the recant reports, haa originated from sources linked with Somoaa, Tbe Coata Rlcan and Guatemalan governments have been ln the position of making defensive denials. No clinching proof of the allegations of any of theae parties has been given,
