Prior to the outbreak of World War I, there had been controversy as to whether lances or sabres were the more effective "armes blanches" (i.e., edged weapons) for cavalry, but neither proved a match for modern firearms. Some armies continued to use lances throughout this war, but they seldom saw use on the Western Front after initial clashes in France and Belgium in 1914. On the Eastern Front, mounted cavalry still had a role and lances saw limited use by the Russian, German, and Austrian armies.
