Poland captured large numbers of M1902 guns in a course of the Polish-Soviet War and impressed them into service as a standard piece of the mounted artillery, designated "76,2 mm armata wz.1902". In 1923, there were 568 guns wz.1902 in inventory. Most were converted to wz.02/26 guns in 1926-1930 (see below), however, Poland also retained some of the guns in the original 76 mm caliber to use existing stocks of ammunition. There were 89 of original guns available at the outbreak of World War II, among others, the sole gun used during the Battle of Westerplatte on 1 September 1939.
