Wz. 19 (pattern 19) was one of the first uniforms used by Polish Army during 1918-1939. Based on British and French designes wz. 19 included many „patriotic” elements – for example Polish eagle symbol or iconic four-cornered cap, called „rogatywka”. Differences between officer and infantry uniforms were very siginificant, making those two patterns quite distinctable. Despite many flaws and disadvantages wz. 19 was still used by Polish forces in defensive efforts in the course of September 1939, because planned uniform unification was stopped by the outbreak of the World War II.
During interwar period Polish Infantry was armed mostly with 7.92mm caliber Mauser carbines, standard bolt-action rifle. Some of the units, mainly reserve and Bataliony Obrony Narodowej (National Defence Batalions) were equiped with Russian-made Mosins or French-made Lebels, due to the lack of basic weapons. As a automatic rifle support weapon Polish forces were armed with redesigned wz. 28 Browning, based on B.A.R. - provided infantry with sufficient and reliable firepower.
Polish Army was well trained, ready to defend it's fatherland. Unfortunetaly German forces outmatched and outnumbered defenders both on land and in the air. Despite that the September Campaign lasted for over a month and the brave Poles fought the Blitzkrieg longer that anyone expected. Even outnumbered and surrounded, like in Modlin, they stood tall against German offensive. For over two weeks Polish Army hold their positions, against overwhelming enemy forces. Only the lack of food, medicine and amunition could forced them to surrender.
