The story I heard was the Argies were caught between a Gurkha unit and the Scottish Black Watch. The Argies took the easy way out and committed suicide.
On another note the Marine unit I was with did a training op with the Gurkha's in 87. We got our backsides handed to us in a very big way by them.

Does this kind of, um... event lead to changes/improvements in Marine training?
Not quite. They surrendered rather quickly, which REALLY disappointed the Gurkhas, who'd been spoiling for a bit of sport after the Argentines opened fire on them with artillery.
The unit on Mt Tumbledown was the 2nd Scots Guards, commanded by Lt. Col. M. I. E. Scott, who received a DSO for his actions. The Gurkha unit was the 1/7th Gurkha Rifles on nearby Mt. William,who found it more-or-less unoccupied when they came to pay their respects to the Argies stationed there, along with units of the British 5th Infantry Brigade.
