"...in 1941, the 2nd Battalion The Argyll and Sutherland Highlanders were in Malaya when war with Japan broke out. Stationed over 300 miles north of Singapore on the Thai border, their task was to provide the rearguard to the withdrawals. Outnumbered and ill-equipped, they fought with outstanding determination.

In January 1942 at Slim River, the regiment was so depleted by a Japanese tank attack that only scattered groups survived. Several of these groups fought on in isolation in the jungle. The remainder, with only three officers and 90 soldiers under Captain Tom Slessor, began the withdrawal to Singapore.

After a return to and reinforcement in Singapore, this group was joined by courageous Chinese volunteers and a party of Royal Marines who were survivors of the battleships HMS Prince of Wales and HMS Repluse. This fighting combination quickly gained the nickname the 'Plymouth Argylls'. With the pipers playing A Hundred Pipers and Highland Laddie, the Argylls eventually crossed to Singapore Island and the causeway was blown.

Two weeks later, the few survivors were taken prisoner and the heroic 2nd Battalion The Argylls and Sutherland Highlanders ceased to exist. Isolated groups fought on in the jungle until they were captured. However, two men, Private Stewart and Private Bennett, remained at liberty for four years, until the return of British forces to Malaya."

It was from this action that a special association was developed & maintained through the years between the A&SH's and the Royal Marines.

Thanks for the headers, I'll have to look for it!
