A few information about general Baryła, then, they might be useful. They are mostly from Polish Wiki, but I couldn't find a better source on line.
Born in 1924 (so he is 65 in 1989), served in Polish People's Army (Ludowe Wojsko Polskie - LWP) since 1945, originally in artillery, since 1949 as political officer. Chief of Main Political Directorate of LWP in 1980-1986, member of Military Council of National Salvation (WRON), member of the Central Comitee of PZPR (Polish communist party) in 1982-1988, member of the Politcal Bureau in 1986-1988, removed from PB in 1988 (when Jaruzelski decided to start talking to the Solidarity), sent as an ambassador to to Syria
Sorry. I didn't noice that fact earlier. But it is possible to keep him in Poland and closer to power; perhaps he manages to deceive Jaruzelski that he might agree to talks with the opposition, while in true he would be preparing a coup. It would be a failure, IMO, but hey, who knows?
