Ratu Sukuna had little time to settle down to his studies. World War I broke out and Sukuna applied for enlistment in the British Army. The British government, however, had a policy of refusing enlistment to Fijians, a policy rationalised by a wish to avoid exploiting the native people. Believing that Fijians would never gain the respect of their British rulers, without proving their worth on the battlefield, Sukuna enlisted in the French Foreign Legion instead. He fought bravely and was wounded towards the end of 1915 and forced to return to Fiji. He returned to France the following year, however, with the Native Transport Detachment, a newly formed contingent assisting the British Army. Apparently, the British colonial authorities had had a change of heart about native participation in the war. For his wartime service, Ratu Sukuna was awarded the Croix de Guerre.
