On 25 June 1918,
Count Mirbach informed his boss, State Secretary of the German Foreign Ministry
Richard von Kühlmann about the deep political crisis of the Bolshevik government: "Today, after more than 2 months of careful observation, I don't think I can make a more favorable diagnosis of Bolshevism: we, no doubt, are at the bedside of a seriously ill patient; and although moments of apparent improvement are possible, ultimately it is doomed." In May, he sent a telegraph to Berlin saying "the Entente allegedly spends huge sums to bring the right wing of the Socialist Revolutionary Party to power and resume the war... Sailors on ships... are probably bribed, like the former Preobrazhensky regiment. Weapons stocks... from weapons factories in the hands of the Socialist Revolutionaries." German diplomat Carl von Botmer also testified that the German embassy, beginning in mid-June 1918, repeatedly received threats that the Bolshevik security service had investigated, but to no avail.
Yakov Blumkin, a Left SR in charge of the Cheka counter-espionage section dedicated to monitoring the activity of the Germans, and Nikolai Andreyev, a photographer the same section, received an order from Maria Spiridonova on 4 July, to carry out the assassination of the German ambassador in two days time. The day of the uprising was chosen, among other reasons, because it was the Latvian national holiday Ivanov Day (
Jāņi), which was supposed to neutralize the
Latvian units most loyal to the Bolsheviks. The Leadership of the Left SRs believed this assassination would lead to a widespread popular uprising in support of their aims. They claimed to be leading a revolt against the peace with Germany and not necessarily against the Bolsheviks and soviet power. On 6 July 1918, at about 1:00 PM, a member of the Left SR central committee, probably
Maria Spiridonova, handed over weapons and instructions to the assassins. Blumkin and Andreyev hid the pistols and grenades in briefcases and drove in a Cheka car to the German embassy, where they arrived at 2:15 PM. They showed a letter of introduction, supposedly signed by the head of Cheka
Felix Dzerzhinsky and asked to see the German envoy. Mirbach believed that the Chekists were coming to inform him of a plan to assassinate him, a plan he had been warned about earlier. During their conversation - at about 2:50 PM, Blumkin drew up a revolver and shot at
Count Mirbach, Dr.
Kurt Riezler, and the interpreter, Lt. Mueller, but failed to injure any of them. Riezler and Mueller took shelter under a large table, whereas Mirbach, who tried to escape, was then shot by Andreyev. The assassins jumped out of a window while throwing grenades to create confusion; Blumkin fractured a leg in the jump and was injured by one of the embassy sentinels. The pair fled and disappeared in a car that was waiting for them in front of the embassy, heading straight for a Cheka HQ (under the command of Dmitry Popov) where the Left SR central committee was waiting. They made many mistakes during the assassination: they left a briefcase at the scene containing certificates in the name of Blumkin and Andreyev; Riezler and Mueller, witnesses to the murder, also survived. In the turmoil, Blumkin and Andreyev even left their caps at the embassy. That same afternoon, Lenin had sent some of the few remaining forces in the city to the northeast, to try to quell the
Yaroslavl uprising, which had just broken out. Only a few Latvian marksmen units, Cheka forces and some Red Guard and Army units (still in training), remained in Moscow. Lenin received the news shortly after, not knowing who had perpetrated the attack, and immediately went to the embassy to apologize for the murder and try to calm the Germans. Later that night, when going to give condolences to the embassy, Dzerzhinski indicated that the authors were socialist-revolutionary members of the Cheka. At the same time, the Foreign Commissioner,
Georgy Chicherin, communicated to him the German demand to station troops in Moscow. A few weeks later, on 30 July, the commander of German occupation forces
Hermann von Eichhorn was assassinated in
Kiev, by the Left SR
Boris Donskoy. == First skirmishes ==
