That's one way of looking at it.
However, if anyone is really interested in the record of the Polish troops of the period the study should begin with the partition of Poland by Prussia, Russia, and Austria in the 1790s.
Poles fought for the French during the Wars of the French Revolution and continued through 1815.
Without Napoleon there would have been no Duchy of Warsaw and Russian attempts at taking over the Duchy was one of the main reasons for the invasion of Russia in 1812. The French referred to it as the Second Polish War.
And no one held a gun to the heads of the Poles to fight with the French and for Napoleon from 1807 onwards. Some Polish units were taken into French pay and the French supported the Poles in establishing their own army in 1807.
The Poles were still pro-French post-1815 and it should be remembered that the overwhelming majority of the Poles had little or no taste to have the Tsar as their sovereign, and that was one of the reasons for the Revolution of 1830 in Poland, and the Russian desire to keep Poland lasted into the 20th century.
