The Prince of Wales and Prince Harry have met relatives of veterans of the Gallipoli Campaign who 100 years ago were on the eve of what turned out to be one of Britain's worst military disasters.
The royals were on the flight deck of the Royal Navy's flagship HMS Bulwark in Turkey's Dardanelles straits, the same crucial waters that the Allies in the First World War hoped to control.
The ship is to be sent to assist operations in the Mediterranean Migrant crisis.
The idea to knock the Ottomans out of the war and open a sea route to Russia was Winston Churchill's but because of hopeless planning, hostile conditions and heroic defending, eight bloody months later the operation was halted, having cost 58,000 Allied lives.
Some 87,000 Turks died defending their home soil.
