Thanks Archer, thats been of great interest!! To anyone whose interested, I`ve discovered the follow.....
The “first line” Territorials, however, were still abroad: indeed the 1/4th had at last, after over 4 years of garrison duty, seen something of active service on the Indian Frontier. It had moved up to the Frontier early in 1918, being stationed at Quetta where it remained until detailed in May 1919 for operations against the Afghans. The chief action in which it took part was the capture on May 27th 1919 of the Afghan position at Spin Maldak, about the strongest post in Afghanistan, in which the battalion was at last given a chance of disguising itself. It took its chances to some purpose, the position being stormed after an action lasting over eight hours in the hottest weather. The Afghan resistance was stubborn, but so well did the 1/4th fight that the Brigadier, B-Gen J L R Gordon, presented it was the drums capture from the enemy as a memento. After this action the battalion remained on active service until the conclusion of the peace with Afghanistan in September. It then returned to Quetta and was placed on orders for home in October, eventually leaving for Karachi on October 30th 1919, just years since its departure to India.
