. The mutiny was led by the ship's
political commissar,
Captain of the Third Rank Valery Sablin, who wished to protest against the rampant corruption of the
Leonid Brezhnev era. His aim was to seize the ship and steer it out of the
Bay of Riga, to
Leningrad through the
Neva River, moor alongside the
museum ship Aurora, an old symbol of the Russian revolution, and broadcast a nationwide address to the people from there. In that address, he was going to say what he believed people publicly wanted to say, but could only be said in private: that socialism and the motherland were in danger; the ruling authorities were up to their necks in corruption, demagoguery, graft, and lies, leading the country into an abyss; communism had been discarded, and there was a need to revive the
Leninist principles of
justice. On the evening of , Sablin lured the captain to the lower deck, claiming that there were some officers who needed to be disciplined for being drunk on duty. When the captain arrived at the lower deck, a fist fight ensued in which Sablin detained the captain and the other officers in the forward sonar compartment and seized control of the ship. Sablin then summoned a meeting of all the senior officers on the ship. Here a vote was taken amongst the fifteen officers present. Sablin informed the officers that he planned to steam to Leningrad and broadcast his revolutionary message. Eight officers voted in favor of the mutiny; the remaining seven senior members of the ship's crew who did not wish to go along with the plan were brutally beaten and locked in a separate compartment below the main deck. Sablin then moved on to the next phase of the plan, which was to win the support of the seamen, numbering about 145-155 men. Sablin was a popular officer and he used this to his advantage. He assembled the crew and delivered a speech which instantly had all the seamen motivated and excited about a revolution. One of the officers who had voted in favor of the mutiny had escaped under the cover of night and had run across the naval dock to raise the alarm; however, the guard at the gate did not believe him. Both the officer and guard were later brutally beaten, arrested, imprisoned, starved, tortured and interrogated by the
KGB. On discovering that they might soon be detected, Sablin decided to set sail immediately, rather than wait till the morning and leave with the rest of the fleet, as originally planned. The crew immediately set sail under the cover of dark and made their way out of Riga. Sablin also ensured that the radar was off to avoid detection from Soviet forces. (including three
Yak-28 bombers, this being the only instance of a Yak-28 firing in anger), which dropped 250 kg bombs in the vicinity of the rebel ship. The aircraft also strafed
Storozhevoy repeatedly. The ship's steering was damaged and she stopped dead on the water from Swedish territorial waters and from Kronstadt. After warning shots from the closing loyal warships, the frigate was eventually boarded by
Soviet marine commandos. By then, Sablin had been non-fatally shot in his leg and detained by members of his own crew, who also unlocked the captive captain and officers. All of the complement from
Storozhevoy, including the captain, were brutally beaten, arrested, starved, tortured and interrogated by the KGB. But only Sablin and his second-in-command, Alexander Shein, a 20-year-old seaman, were tried and convicted. The ship's crew was then changed completely. At his trial in July 1976, Sablin was convicted of high treason and was executed by firing squad on , while Shein was sentenced to prison and was released after serving eight years. The rest of the mutineers were set free, but dishonorably discharged from the Soviet Navy. == Aftermath ==
