World War I Victoria Cross Recipient. A native of Ireland, he received the award posthumously (delivered to his mother's residence in Dorchester, Dorset, England) in September 1915 for his actions as a captain in the 1st Battalion, The Royal Inniskiling Fusiliers, of the British Army on 1/2 July 1915 near Krithia, Turkey during the Gallipoli Campaign. Born in Frankfield, Douglas, County Cork, Ireland, his father was a career soldier in the Argyll and Sutherland Highlanders of the British Army. Following his graduation from Wimbledon College at Wimbledon, London, England in 1906, he attended the British Royal Military Academy at Sandhurst and in 1909 he received a commission in The Royal Inniskilling Fusiliers. He was then stationed in China until 1912 when he was assigned to British India. Following the outbreak of World War I in July 1914, he returned to England, promoted to the rank of captain, and was sent to Mideast where in April 1915 he participated in the invasion of Gallipoli, Turkey, winning the Victoria Cross for gallantry in early July and was wounded. He was then sent to Egypt to recover and the following month he returned to his unit at Gallipoli and during an assault on Scimitar Hill, near Suvla, Turkey, he went missing in action. His body was never found and he was presumed dead. His Victoria Cross citation reads: "Captain Gerald Robert O'Sullivan, 1st Battalion, The Royal Inniskilling Fusiliers. For most conspicuous bravery during operations south-west of Krithia, on the Gallipoli Peninsula. On the night of the 1st-2nd July, 1915, when it was essential that a portion of a trench which had been lost should be regained, Captain O'Sullivan, although not belonging to the troops at this point, volunteered to lead a party of bomb throwers to effect the recapture. He advanced in the open under a very heavy fire, and, in order to throw his bombs with greater effect, got up on the parapet where he was completely exposed to the fire of the enemy occupying the trench. He was finally wounded, but not before his inspiring example had led on his party to make further efforts, which resulted in the recapture of the trench. On the night of 18th-19th June, 1915, Captain O'Sullivan saved a critical situation in the same locality by his great personal gallantry and good leading." His Victoria Cross is on display at The Lord Ashcroft Gallery of the British Imperial War Museum in London, England.
