On May 12, 1935, Marshal Józef Piłsudski died. He was buried at Wawel, in the crypt under the Tower of Silver Bells.

On the night of 6 to 7 July (24/25 June old style) 1866, 5,000 kilometres east of their homeland, a group of January insurgents sent to Baikal for penal labour stirred up a rebellion, disarmed their guards and tried to forge an escape route to Mongolia.
