To M.K.,
I am a newcomer to Wikipedia, so whether what I referred to was or was not a proper source, there are sources within that internet page, and I thought the article's editors might want to be given a heads up on errors and follow up.
The French experts who took a census for the Versailles Peace Conference found only 20% of the Vilnius region to be Poles, and the Poles did not dispute that, but were very pleased with that number.
To give you one specific example of how the fraudulent Zeligowski "plague" affected the census statistics: In Punsk in the 1919 census there were 4,666 Lithuanians and 25 poles. But after Zeligowski's plague descended on the Lithuanians, in 1921 there were only 1,689 Lithuanians left, but apparently because of the Poles' miraculously increased fertility rate, the population of Poles went from 25 in 1919 to 3,068 in 1921. And, of course, in the official government records all the former Algirdas were now named Olgerd, the former Vytautas were now Witold, and so forth. They were, of course, the same people as they were before, just re-baptized with new names and new ethnicity.
Please recall, that not only was Zeligowski's "mutiny" a fraud, which Pilsudski later publicly confirmed was really part of the Polish government's hidden imperialistic policy, but it was also carried out within a day after the Poles had signed the armistice with Lithuania in Suvalkai, and was a violation of that armistice treaty. The preparations for Zeliogowski's "mutiny" were, in fact going on while the Poles were at the negotiating table with the Lithuanians. So, falsification and fraud was part of Poland's government action at that time, and this continued in census statistics after the plague. Any scholarly encyclopedia should not overlook such basic uncontroverted facts. --Orintas (talk) 16:25, 19 November 2009 (UTC)
