The LWP also took part in the suppressing of the 1968 democratization process of Czechoslovakia, commonly known as Prague Spring. As the operation against Czechoslovakia, columns of tanks and motorized rifle troops of the LWP headed toward Prague and other major centers, meeting no resistance. The 28,000 troops of the Polish 2nd Army from the Silesian Military District, commanded by general Florian Siwicki, were the main Polish force.
