The deeply unpleasant Korean War began in 1950 with an unprovoked attack by North Korea. Hostilities went on for three long years followed by an uneasy armistice that continues to this day. United Kingdom casualties amounted to some 300 Officers & 4 000 Other Ranks many of them conscripts while a total of over 100 000 United Nations soldiers were killed & three times that number wounded.A Royal Engineer Field Squadron deployed to Korea in late 1950 & this was expanded to a Regiment the following year. Often involved in fierce fighting the Sappers suffered grievous casualties including 42 killed & several hundred wounded. Their gallantry was rewarded by numerous awards including a CBE an OBE & eight MBEs two DSOs thirteen MCs eight MMs & most notably a Distinguished Conduct Medal second only to the Victoria Cross. It was a vicious war whose intensity neverslackened; in the last two months alone the Communist artillery fired over 700 000 rounds against just under five million fired back by United Nations forces. The Royal Engineers among them the Author were indispensible at all levels from the forward areas where they were often involved in close-quarter fighting right back to the base in Japan. Their skills & roles varied from patrolling river crossing & road building to mine-clearing & -laying defence works bridging & postal services so vital for morale. Other tasks included blowing things up (always a favourite occupation) & clearing booby traps (less popular). In a war zone with one of the most inhospitable climates in the world merely keeping alive was a challenge. This book is not merely a gripping yet thoroughly readable account of the Sappers achievement but a tribute to the sacrifice of those who did not return.
