A Polish 7TP (Seven tonne - Polish) tank participating in the 1938 joint military exercises in Pomerania.
Polish Tanks were largely indigenously produced both prior to and during the course of the Weltkrieg, as a result of the Germans declining to support King August's government with tanks of their own. The 7TP model, a lightly armed but swift vehicle, its Swedish 37mm Bofors main gun would nonetheless prove to be an asset to Poland, most particularly when the Poles and Lithuanians revolted in 1940. German troops inside Poland proper were rapidly overwhelmed in large part due to the fact that in a twist of fate, the Polish tanks were actually better than the outdated relics used by German garrison forces.
The revolt lasted 240 days before being supressed, and though Poland suffered greatly before it was liberated, the Internationale was appreciative of the efforts Poland had gone to during the war, and as such during the deliberations of the 2nd Copenhagen Conference, Poland was awarded the entirety of former Galicia and Lodmeria, its disputed territories in Belorussia and Ukraine, and the regions of Posen, Silesia, West Prussia and Danzig. Ironically, its previously bitter territorial dispute with Lithuania was resolved in the aftermath of the Weltkrieg, with the two new Socialist governments agreeing to degrees of autonomy and language rights for the regions Polish population.
Though relatively few 7TP tanks survived the 2nd Weltkrieg, a few (One complete and three partial), wound up at the Nancy People's Tank Museum post war, where they can be seen today.
