RN Subs

Keith Hall

The X and XE-Class submarines were conceived during the Second World War: around 51ft (16m) long, they were designed to be towed by a mother submarine and use their small size to complete stealth missions, such as attacking harbours and performing reconnaissance. Although they would not begin active service until 1942, the submarine crews achieved quite the record, racking up 167 honours between them, including four Victoria Crosses.

It was the Italians who pioneered the use of two-man human torpedoes or 'chariots', and their attacks on ships of the Royal Navy in Alexandria Harbour in 1941 caused Winston Churchill to write to the Chief of Staffs committee to enquire what was being done to emulate these daring attacks.

The result was the development of British 'chariots' which were regarded as stop-gaps until the X-Craft or midget submarines could be deployed.

July 1945. Eighteen young British, Australian and New Zealand special forces from a top-secret underwater warfare unit prepare to undertake three audacious missions against the Japanese.

Using XE-craft midget submarines, the raiders will creep deep behind Japanese lines to sink two huge warships off Singapore and sever two vitally important undersea communications cables. Success will hasten ultimate victory over Japan; but if any of the men are captured they can expect a gruesome execution.

Can the Sea Devils overcome Japanese defences, mechanical failures, oxygen poisoning and submarine disasters to fulfil their missions? Mark Felton tells the true story of a band of young men living on raw courage, nerves and adrenalin as they attempt to pull off what could be the last great raid of World War Two.
