Suitable field and rail carriages were built for these guns in an effort to give their forces the heavy field artillery needed to overcome trenches and hardened concrete fortifications. In August 1914 the heavy field artillery regiments "(artillerie lourde de campagne)" were equipped with 5 regiments of modèle 1890's, with 3 batteries per regiment, and 6 howitzers per battery for a total of 90 howitzers. Each regiment was provided with 400 rounds of ammunition and the available ammunition supply was 1,280,000 rounds. The modèle 1890's were used until they either wore out or were destroyed.
