The Chargé in Costa Rica (Thurston) to the Secretary of State
[Received March 4—11:40 p.m.]
31. Contents of Department’s 10, February 28, 9 p.m.67 have been conveyed to Minister for Foreign Affairs. He again expressed appreciation of friendly concern manifested by the United States and assured me orders will be given immediately to Costa Rican forces to avoid further contact with Panaman forces where such action does not involve movements incompatible with national dignity.
I informed him of rumored intention of Costa Rica to invade region of Almirante Bay to which he replied that the report might [Page 177] be true adding that such a movement merely would be a justifiable reprisal. Inasmuch as 1,000 soldiers with corresponding equipment and artillery have been sent to Port Limon within last 48 hours I felt it to be in accordance with instructions to state that any advance by Costa Rican forces beyond recognized boundary would be most regrettable and would undoubtedly weaken Costa Rica’s cause.
It is respectfully suggested that if Panama complies with suggestion to retire troops that fact be promptly communicated to me for the information of Costa Rican Government. Popular enthusiasm for war has been stimulated by reported engagement at Coto and this may make it difficult for President Acosta to withdraw forces or suspend military activities until populace knows Panama has already done likewise.
