In Polish service, the Canon de 105 mle 1913 Schneider was given the designation "105 mm Armata wz. 13." The first Polish unit to use the wz. 13 was General Józef Haller's "Blue Army" that was created in France in 1917. The Blue Army received 16 guns which armed two Heavy Artillery Regiments. When World War I ended the Blue Army returned to Poland with their guns. In the spring of 1919 Poland bought 12 of the similar "Cannone da 105/28" produced under license in Italy by Gio. Ansaldo &amp; C. By the end of the Polish-Soviet War 64 wz. 13's had been delivered by France and between 1923 and 1927 another 54 wz. 13's were purchased.
