Ryszard Kukliński

A colonel in the Polish army, codenamed Jack Strong, who gave the CIA around 40,000 pages of documents concerning the Polish People's Republic between 1971 and 1981. From the spring of 1981 he was head of the team planning martial law, which made him the West's window on the crackdown being prepared against Solidarity. CIA officers flew him, his wife and two sons out of Poland on the night of November 7 to 8, 1981, about a month before martial law was declared. A Warsaw military court sentenced him to death in absentia in 1984. Poles have long argued over whether he was a traitor or a patriot; Poland's Supreme Court quashed the sentence in 1995, and he died in Tampa, Florida, in 2004.
