The recent opening of the Armed Forces Memorial is reminder that casualties continue to this day. The Korean Conflict is an oft forgotten war, where Britain lost many service personnel: http://www.britains-smallwars.com/korea/index.html This database seems to list everyone of these losses, and it appears (though I haven't checked all of them) to have a photograph of each casualty's memorial plaque: http://www.uk.or.kr/wargrave/
Just checked the figures for British casualties and it does seem that all the British killed are listed. The consensus seems to be that there were 1,078 killed in action, 2,674 wounded and 1,060 missing or taken prisoner.
The Korean War is a forgotten war. It took place many thousands of miles away, while life in Britian carried on as normal. Anthony Farrar-Hockleys book, The edge of the Sword, gives a vivid picture of life in Korea at the start of the conflict and as his time as a prisoner. Max Hasting wrote a good general account but like some many histories of the war, the realse of 104 telegrams concerning the outbreak of the war by Boris yeltsin, the chapters on the origins of the war are dated.
