Note of the Government of the USSR,
According to information received from the headquarters of the Red Army, our troops posted on the Carelian Isthmus, in the vicinity of the village of Mainila, were the object to-day, November 26th, at 3.45 p.m., of unexpected artillery fire from Finnish territory. In all, seven cannon-shots were fired, killing three privates and one non-commissioned officer and wounding seven privates and two men belonging to the military command. The Soviet troops, who had strict orders not to allow themselves to be provoked, did not retaliate.
In bringing the foregoing to your knowledge, the Soviet Government consider it desirable to stress the fact that, during the recent negotiations with M. Tanner and M. Paasikivi, they had directed their attention to the danger resulting from the concentration of large regular forces in the immediate proximity of the frontier near Leningrad. In consequence of the provocative firing on Soviet troops from Finnish territory, the Soviet Government are obliged to declare now that the concentration of Finnish troops in the vicinity of Leningrad, not only constitutes a menace to Leningrad, but is, in fact, an act hostile to the U.S.S.R. which has already resulted in aggression against the Soviet troops and caused casualties.
The Government of the U.S.S.R. have no intention of exaggerating the importance of this revolting act committed by troops belonging to the Finnish Army – owing perhaps to a lack of proper guidance on the part of their superiors – but they desire that revolting acts of this nature shall not be committed in future.
In consequence, the Government of the U.S.S.R., while protesting energetically against what has happened, propose that the Finnish Government should, without delay, withdraw their troops on the Carelian Isthmus from the frontier to a distance of 20-25 kilometres, and thus preclude all possibility of a repetition of provocative acts.
Accept, Mr. Minister, the assurance of my high consideration.
People's Commissar for Foreign Affairs of the USSR
