The Governor-General thus wrote to Edwardes:

'Prospects of a war between Russia and Turkey are watched with interest by all.... In England they are fidgety regarding this border beyond all reason, and most anxious for that declared amity and that formal renewal of friendly relations which you advocate in your letter.'

The balance of Indian opinion, however, was against our making overtures to Dost Mahomed. John Lawrence, at that time the great power in the Punjab, was altogether opposed to Edwardes's policy in this matter. He admitted that it might be wise to renew intercourse with the Kabul ruler if he first expressed his regret for previous misunderstandings; but later he wrote to Edwardes:

'I dare say you are right; still, I cannot divest myself of the idea that it is a mistake, and will end in mixing us up in Afghan politics and affairs more than is desirable. The strength which a treaty can give us seems to be a delusion. It will be like the reed on which, if a man lean, it will break and pierce his hand.'

John Nicholson, Outram, and James Abbott agreed with Lawrence. They urged that any advance on our part would be looked upon as an indication of conscious weakness; and the probability was that an arrogant, irritated Mussulman ruler would regard an overture as a proof of our necessity, and would make our necessity his opportunity. But Lord Dalhousie, while anxious to avoid any communication being made which could be liable to misconstruction, saw neither objection nor risk in opening the door to reconciliation, provided no undue anxiety was displayed on our part. The Governor-General practically left the matter in the hands of Edwardes, who lost no time in trying to attain the desired object. The greatest forbearance and diplomatic skill were necessary to bring the negotiations to a satisfactory termination, but they were concluded at last, most successfully, and to Edwardes alone is due the credit. It is instructive to read the full [record][1] of this tedious and difficult piece of diplomacy, for it serves as an interesting example of Oriental subtlety and circumlocution, contrasted with the straightforward dealing of a high-minded Englishman.

The Amir wrote a letter to the Governor-General couched in most satisfactory terms, which he forwarded to Peshawar by the hand of his confidential secretary, and which received, as it deserved, a very friendly reply. This resulted in Dost Mahomed sending his son and heir-apparent, Sardar Ghulam Haidar Khan, to Peshawar, and deputing him to act as his Plenipotentiary in the negotiations. Ghulam Haidar Khan reached Peshawar in March, 1855, where he was met by the Chief Commissioner, and on the 30th of that month the treaty was concluded. 'It guaranteed that we should respect the Amir's possessions in Afghanistan, and never interfere with them; while the Amir engaged similarly to respect British territory, and to be the friend of our friends and the enemy of our enemies.'

The Governor-General had at first resolved to entrust to Edwardes the duty of meeting the expected Envoy from Kabul, and orders to that effect were issued. But Edwardes, more anxious for the success of the negotiations than for his own honour and glory, wrote to Lord Dalhousie suggesting that the Government of India should be represented by the Chief Commissioner of the Punjab, and promising to afford Sir John Lawrence all the assistance in his power. Edwardes believed that the importance of the treaty would be enhanced in the eyes of the Afghans by the presence of the higher official; and in this opinion the Governor-General concurred. On the conclusion of the treaty, Lord Dalhousie wrote to Edwardes: 'I congratulate you and myself and all else concerned on this successful issue of the negotiations, which have now lasted just a year.'

This treaty of March, 1855, was only preliminary to that for the ratification of which the Amir came in person to Peshawar the following year.

Towards the end of 1855 Dost Mahomed found himaelf in considerable difficulties, and appealed to us for assistance. A revolt had occurred at Herat, and a Persian army was preparing to besiege that fortress; the chiefs and people of Kandahar were disaffected; and the province of Balkh was threatened with invasion both by the King of Bokhara and by Turkoman hordes. The Amir looked upon Herat as an integral part of the Afghan dominions, and was very desirous of re-establishing his authority over that place and preventing its falling into the hands of the Persians; but he felt himself too weak to have any hope of success without help from us in men and money. It was, therefore, Dost Mahomed's interest to convince the British Government that the Shah had infringed the conditions of an engagement entered into with us in 1853, under which Persia abandoned all claim to Herat. The Amir thus hoped to establish a quarrel between England and Persia for his own benefit, and to secure our assistance against the latter power. To further this design, Dost Mahomed offered to come to Peshawar and consult with the British authorities. Edwardes was in favour of the proposed visit. John Lawrence was opposed to it, saying he did not think much good would result from such a meeting, because it could hardly be anticipated that the views of the Amir and the British Government would coincide, and if Dost Mahomed should fail to obtain what he wanted, his dissatisfaction would be a positive evil. The Governor-General admitted the force of these objections, but in the end considered that they should be set aside if the Amir was in earnest in desiring a consultation. 'A refusal or an evasion to comply with his wish,' Lord Dalhousie thought, 'might be misunderstood, and although a meeting might lead to disappointment and disagreement, it would, at any rate, put the relations of the British Government with the Amir, as regards Herat, upon a clear footing.'

War with Persia While this discussion was going on, the advance of a Persian army for the purpose of besieging Herat, coupled with the insults offered to the British flag at Teheran, led to the declaration of war between England and Persia. The Chief Commissioner was therefore directed to tell the Amir that he would be paid a periodical subsidy to aid him in carrying on hostile operations against Persia, subject to certain conditions. On receiving these instructions, the Chief Commissioner directed Edwardes to invite the Amir to an interview. Dost Mahomed accepted the invitation, but before the auspicious meeting could take place Lord Dalhousie had left India, and Lord Canning reigned in his stead. Lord Dalhousie resigned on the 29th February, 1856, after having filled the arduous and responsible position of Governor-General for no less than eight years, adding year by year fresh lustre to his splendid reputation.
