Pass is swept from end to end by hurricanes of wind and rain and snow. At the very time when these storms usually occur we had a dozen regiments and batteries straggling along the whole length of the Bolan Pass. Last year, however, there was neither snow nor hurricane, and our troops got through the Pass in safety. There was no opposition offered to our advance on Kandahar, but, from the want of food and the hardships which had to be endured, no less than twenty thousand camels perished upon the march. This mortality decided the campaign. When General Stewart reached Kandahar the situation was as follows:--The magazines at Quetta were nearly empty. Four months' food was collected at Sukkur, but awaited carriage for its transport to Quetta. The third column under General Primrose was assembling on the Indus, and needed ten thousand camels to enable it to advance. To supply all these wants there were at Sukkur about 1600 camels. In order to lessen the pressure on the Commissariat, General Stewart divided his forces, despatching one column to hunt for supplies in the direction of Giriskh, and sending another with the same object to Khelat-i-Ghilzie. These movements caused the death from cold and hunger of a large additional number of camels, and demonstrated that there was not food in that part of Afghanistan sufficient for a force so large as that collected at Kandahar. Sinde, meanwhile, had been swept so bare of camels that it was impossible to collect a sufficient number for the carriage of food to Quetta before the hot weather had set in, and the march across the desert was barred by "the blast of death." Immediate action was necessary if General Stewart's troops were not to starve; and eight thousand men returned to India, reducing the garrison left at Kandahar to four thousand. This number, it was trusted, the Commissariat would be able to feed during the hot weather. But even this small force was so scantily supplied with carriage that it could not have moved, in a body, for fifty miles in any direction. It was, so to speak, nailed to the spot on which it was encamped. This want of food, far more than the physical difficulties of the country, is and always will be the insuperable obstacle to carrying on extensive military operations in Afghanistan. The people obtain no more from the soil than just suffices for their own wants; and for days together an invading army has to pass over huge wastes with hardly a trace of human habitation, and consequently destitute of food.
