The mle 1877/14 was considered an adequate gun which served throughout the First World War and provided the French Army with heavy artillery when needed most. Between wars, it was assigned to garrison duty and was used until the Second World War. Some received pneumatic tires, but the absence of a sprung suspension limited their towing speed. After the surrender of France in 1940 guns captured by the Germans were used as coastal artillery by occupation units with the designation "15.5 cm Kanone 422(f)".
