When World War I began approximately 80 guns were still available.
They constituted the only true heavy artillery the British army possessed, and were heavily engaged in the early battles in France and Flanders.
It was adapted to use the standard 100 pounds (45.36 kg) gun shell, with a slight enlargement of the chamber to produce Mk I*, allowing slightly larger propellant charges.
It served in all theatres, including the Western Front, until replaced by the modern 6 inch 26 cwt howitzer from late 1915.
At Gallipoli, where there was a lower priority for modern ordnance, the 6 inch 30 cwt was used at Helles by 14th Siege Battery RGA (4 guns), attached to 29th Division, and at Anzac by the Australian 1st Heavy Artillery Battery (2 guns from the Royal Malta Artillery, crewed by the Royal Marine Artillery, which arrived in May).
