On Sunday, 9 January 1905, Nijinsky was caught in the Bloody Sunday massacre in St. Petersburg, where a group of petitioners led by Father Gapon attempted to present their petition to the Czar. Soldiers fired upon the crowd, leading to an estimated 1000 casualties. Nijinsky was caught in the crowd on Nevsky Prospect and propelled toward the Winter Palace. Imperial cavalry troops charged the crowd, leaving him with a head wound. The following day, he returned to the scene with a friend whose sister was missing. She was never found.
