FYI: Ustym Karmaliuk

From Wiki:-

Ustym Yakymovych Karmaliuk (also Karmelyuk; Ukrainian: Устим Якимович Кармалюк (Кармелюк); March 10, 1787 – October 22, 1835) was a Ukrainian outlaw who fought against the Russian administration and became a folk hero to the commoners of Ukraine. He is often referred to as the "Ukrainian Robin Hood" and "the last haydamak".

His grotto

With the ongoing Polish uprising of 1831, by the early 1830s Karmaliuk's guerrilla army was approximately 20,000 strong, with over 1,000 raids on the estates of the Polish and Russian landowners over a 20-year period. The response of the tsar was to station military units in those regions hardest hit by Karmaliuk. He was caught four times and sentenced to hard labor in Siberia, but escaped each time.

A bit bigger than Robin Hood, then. 

According to legend, Karmaliuk was impervious to bullets, but he was killed by the only thing that could get him, a lead garment button.

Beware the Garment Buttons...
