The Ambassador in Greece
(MacVeagh) to the Secretary of State
Subject: Violations of the Greco-Yugoslav Border.
Sir: I have the honor to transmit herewith a copy of a report prepared for the War Department by Captain William H. McNeill, Assistant Military Attaché, concerning recent incidents on the Greco-Yugoslav border, which is of particular interest in relation to the Department’s information telegram No. 693 of July 161 mentioning the likelihood of exploratory raids across this frontier.
The Department will observe that the incidents related are of a more serious character than those reported in my despatch No. 1282 of July 42 both by their nature and since they are apparently directed from a base established in or near Monastir for the express purpose of organizing forays into Greece with the object of stirring up trouble and disseminating Communist propaganda. Already on Greek soil one British soldier has been killed, one wounded, and a third taken prisoner by one of these bands. The Yugoslavs have also adopted an attitude of studied rudeness towards senior British officers desiring to parley about these incidents.
While all reports reaching this Embassy from the Department and other Missions seem to agree that the present Soviet war of nerves is directed more against Turkey than Greece, these violations of the Greek border and the persistent press campaign against Greece would appear to indicate a desire to keep the pot boiling in this area as well. If the Russians decide to risk military action against Turkey, the possibility, discussed in my despatch No. 1331 of July 17,3 of a preliminary or simultaneous drive by Yugoslav, Bulgar, and even ELASite puppet forces across the relatively undefended plains of Northern Greece to the Aegean should perhaps not be excluded.
