You must have missed the bit about ordering the massacre of Lithuanian civilians.
No, I have not missed it, but I do not see any sense in posting this info with a heading like "Polish Innocence". War is war, and (extremely) nasty things happen. Otherwise, we would need to post similar threads with titles like "Jewish Innocence" - Koniuchy, Naliboki (my ancestors were directly involved on the victim side), "American Innocence" (Hiroshima, Nagasaki), "Allies Innocence" (Dresden, Hamburg) etc. etc.
"Between 20-27 Lithuanians were shot in Dubingiai on 23 June, 1944, during World War II by a local Armia Krajowa unit. The crime was supposed to be a retaliation by the Polish commander for an earlier massacre of Polish villagers in Glitiškės by colaborationist Lithuanian police" - from en.wikipedia.org/wiki/Dubingiai
- seems like war is not a clean-cut thing at all, at all. Which does not make it any less terrible.
Rather than discussing who was "innocent" or not, I would rather discuss the choices people had / hadn't when in the army and trying to fight the good fight within constantly shifting borders and changing political alliances, as was the case in the Polish Kresy at that time. Mistakes were made - and paid for, in blood.
