He produced letters from Jellalabad and Peshawur giving information of reinforcements on the way from India, and urging the maintenance of resistance. He argued that to conclude a treaty with the Afghans would be a fatal error, and suggested two alternative courses which offered a prospect of saving their honour and part of the army--the occupation of the Balla Hissar, which was the preferable measure, or the abandonment of camp, baggage, and encumbrances, and forcing a retreat down the passes. The council--Pottinger must have written sarcastically when he termed it a 'council of war'--unanimously decided that to remain in Cabul and to force a retreat were alike impracticable, and that nothing remained but the endeavour to release the army by agreeing to the conditions offered by the enemy. 'Under these circumstances,' in the words of Pottinger, 'as the Major-General coincided with the officers of the council, and refused to attempt occupying the Balla Hissar, and as his second in command declared that impracticable, I considered it my duty, notwithstanding my repugnance to and disapproval of the measure, to yield, and attempt to carry on a negotiation.' This Pottinger accordingly did. The first demand with which he had to comply was to give bills for the great sums promised by the Envoy to the chiefs for their services in furthering and supporting his treaty. This imposition had to be submitted to, since the Afghans stopped the supplies until the extortion was complied with. The next concession required was the surrender of the artillery of the force, with the exception of six field and three mule guns; and the military chiefs endured this humiliation, against which even the demoralised soldiery chafed. Then the demand for hostages had to be complied with, and four officers were sent on to join the two hostages already in Afghan hands. The chiefs had demanded four married hostages, with their wives and children, and a circular was sent round offering to volunteers the inducement of a large stipend; but the sentiment of repulsion was too strong to be overcome by the bribe. The sick and wounded who could not bear the march were sent into the city in accordance with an article of the treaty, two surgeons accompanying their patients.
