On this date in 1863, Zygmunt Padlewski was shot for rebelling against the Russian empire.
A young St. Petersburg-trained tsarist officer with a patriotic bent — his father had taken part in the November  Uprising against Russian domination — Padlewski (English Wikipedia entry | German | the surprisingly least detailed Polish) spent the early 1860s organizing revolutionary exiles in Paris.
He then put his neck where his mouth was by returning to Warsaw to agitate and, eventually, to assume the leadership of Polish rebels in that area during his own generation’s doomed revolution, the January  Uprising.
Padlewski’s carriage was detained at a checkpoint when he tried to sneak back to Warsaw after a defeat, and his too-liberal bribes excited the suspicion of the Cossack sentries — who searched the traveler and discovered they had a man well worth the capturing.
He was shot at Plock, where a street and a school today bear his names (numerous other cities around Poland also honor Padlewski).
