Private David O'Sullivan - Service No: CH / 21243 - Royal Marine Light Infantry Regiment, the son of Denis and Margaret O'Sullivan, from Glenreigh, Ballynol, Tallow, Co. Cork, Ireland. David was born on November 14, 1898, in Ballynoe, Tallow, Ireland.

He joined the Royal Marine Light Infantry, Chatham Division, 4th Royal Marines Battalion on March 30, 1917 at the age of 19. In April 1918 he was involved in a Royal Navy attack on the port of Zeebrugge, Belgium. The plan was to sink three old ships just before the entrance to Zeebrugge and thus make the port unusable as a submarine base. David was part of the Royal Marine Light Infantry Regiment on the HMS Hindustan. As the port approached, the wind changed direction and the smoke screen of the fleet went to sea. The Germans opened fire and the marines were in the wrong place without their heavy weapons and one of their blockade ships was already lost before the entrance to the harbour was in sight. The other two ships were sunk in the wrong place and the harbour was therefore unavailable for only a few days for submarines before the Germans dug a canal around these sunken ships.

About 227 Britons died and 356 were injured; David O'Sullivan was one of the victims on that day, 23 April 1918, he was amongst the missing. A month later his body was washed ashore in the Netherlands after a storm, and he was buried at the Noorderbegraafplaats in Flushing (Vlissingen), The Netherlands, First World War plot, I. 14. To honour him I adopted his grave.
