one the way to Korea

Looks like a group of mainly National Servicemen just disembarked from the troopship - likely the Empire Windrush or Empire Orwell  - moored in the background.

An interesting photo, because the usual route was Southampton to Singapore, then over the causeway to Nee Soon transit camp for a few days to be kitted out with lightweight green - then on to Korea by troopship or - in my case aboard the aircraft carrier HMS Unicorn. These lads still in standard battledress with 'blancoed' puttees and carrying their rifles are probably being marched to Whitfield Barracks to be kitted-out.

Majority of us aged 18 and 19 hadn't even heard of Korea, where it was, why we were going there or what we were fighting for.
