1915, together with 1st Brigade, Polish Legions, Lis crossed the Vistula river, moving eastwards, to Volhynia. In his spare time, Leopold studied French language and read works of Kant, Nietzsche and Spinoza. In January 1915, during a leave in Wadowice, he completed final high school exams. In 1917, after the so-called Oath crisis, Kula was interned, and then drafted into Austrian Army, which sent him to the Italian Front. Some time in 1918 Leopold returned to Galicia, and immediately busied himself with creation of Polish Army. He was of Pilsudski's favourite soldiers, and a very brave soldier. During the Polish–Ukrainian War, he fought both in Eastern Galicia and Volhynia, taking part among others in the Battle of Lwów (1918). In the night of March 6/7, 1919, Kula carried out a successful attack on a Volhynian town of Torczyn, which had been in Ukrainian hands. On March 7 he died from wounds he had received during the night battle. Leopold Lis Kula was at that time regarded as one of the most gifted Polish officers. He was posthumously promoted to Colonel (Pułkownik), and his funeral, which took place in Rzeszów, turned into a patriotic demonstration. Kula was buried at Rzeszów's Pobitne Cemetery; among flowers placed on his coffin was a wreath that said "To my brave boy – Józef Piłsudski". Lis was posthumously awarded Silver Cross of the Virtuti Militari and Cross of Independence (December 19, 1930). Several streets and buildings were named after him, as well as an armoured train Lis-Kula (named so on April 5, 1919). In 1937, Warsaw's 5th Men Gymnasium was named after him, and on March 8, 1939, Polish Minister of Internal Affairs named a settlement near Torczyn "Kolonia Lisa-Kuli". Also in 1939, Lis-Kula was named patron of the 23rd Infantry Regiment from Wlodzimierz Wolynski. His monument is located in Rzeszów.
