In spring 1880, Yakimova was sent to
Odesa, where she and Grigori Isaev were delegated to construct a bomb, which was going to be detonated in a tunnel under Italyanska Street, on the route that the Tsar was expected to take as he travelled from Odessa station to the wharf where his steam boat was docked. This plan was aborted when Isaev accidentally blew three fingers off his hand. Yakimova cleaned and bandaged the injury, took him to hospital, and stayed with him during the operation in case he said anything incriminating while under anesthetic. In February 1881, Narodnaya Volya used the same plan to attempt to assassinate
Alexander II in St Petersburg. Yakimova and
Yuri Bogdanovich, using false passports that identified them as a married couple named Kobozev, rented a shop at 56 Malaya Sadovaya, saying that they wanted to run a business selling cheese, while a team led by
Andrei Zhelyabov dug a tunnel under the street, which they expected the Tsar to use. The ‘Kobozevs’ aroused suspicion because they were well educated but seemed to know very little about cheese, and were visited by police, who failed to spot the tunnel. This plan was abandoned when the Tsar took a different route, and was killed by a team of bomb throwers led by
Sophia Perovskaya. == Prison and exile ==
