On the day the February 1917 Revolution began in Saint Petersburg, Rachmaninoff performed a piano recital in Moscow in aid of wounded Russian soldiers who had fought in the war. He returned to Ivanovka two months later, finding it in chaos after a group of Social Revolutionary Party members seized it as their own communal property. Despite having invested most of his earnings on the estate, Rachmaninoff left the property after three weeks, vowing never to return. It was soon confiscated by the communist authorities and became derelict. In June 1917, Rachmaninoff asked Siloti to produce visas for him and his family so they could leave Russia, but Siloti was unable to help. After a break with his family in the more peaceful Crimea, Rachmaninoff's concert performance in Yalta on 5 September 1917 was to be his last in Russia. Upon returning to Moscow, the political tension surrounding the October Revolution found the composer keeping his family safe indoors and being involved in a collective at his apartment building where he attended committee meetings and kept guard at night. He completed revisions to his Piano Concerto No. 1 among gunshots and rallies outside.
