Setting out at nightfall of December 1, he led the remainder northwards through a side valley, and then up a gully on the side of the Spingawi.
These efforts resulted in the discovery by Major Collett of another practicable gorge further to the north leading up to a neighbouring height, the Peiwar Spingawi, whence the head of the Kotal might possibly be turned.
At dawn the Highlanders and 5th Gurkhas charged the Afghan detachment in its entrenchments and breastworks of trees, and were soon masters of the Spingawi position.
To divide a column, comprising only 889 British and 2415 native troops, and that too in face of the superior numbers of the enemy, was a risky enterprise, but General Roberts determined to try the effect of a night march up to the Spingawi. He hoped by an attack at dawn on the Afghan detachment posted there, to turn the main position on the Kotal, and bring about its evacuation.
