The regiment, which was based in Sialkot in India at the start of the First World War, landed in France as part of the 2nd (Sialkot) Cavalry Brigade in the 1st Indian Cavalry Division in November 1914 for service on the Western Front.
The regiment fought in its conventional cavalry role at the Battle of Cambrai in November 1917.
The regiment was transferred to the 7th Cavalry Brigade, part of the 3rd Cavalry Division in February 1918 and was used as mobile infantry, plugging gaps whenever the need arose, both as cavalry and as infantry during the last-gasp German Spring Offensive.

After the signing of the Armistice on 11 November 1918, the regiment remained in continental Europe, joining the British Army of the Rhine in Cologne, Germany.
The regiment then served in County Cork, Ireland, where it operated against the Irish Republican Army during the War of Independence.
In 1921, the title of the regiment was altered to the 17th Lancers (Duke of Cambridge's Own).
