While still camped outside of
Herat in July 1838, Mohammad Shah realized that he would soon have to withdraw his forces, and thus dispatched a delegation led by Ajudanbashi to Europe in order to meet with high-ranking Austrian, French, and British officials in order to clarify the Iranian government's claims and express disapproval of British interfering in the affairs of Herat. On 13 September 1838, Ajudanbashi and his group departed
Tabriz and traveled across the territory of the
Ottoman Empire. One of the members of this delegation was the scribe
Mirza Fattah Khan Garmrudi, who wrote a travelogue about their journey, entitled
Chaharfasl.
Klemens von Metternich, the Austrian
chancellor, welcomed him warmly in
Vienna and made arrangements to ensure that he would also be welcomed in Britain as a representative of the Iranian government. Ajudanbashi was favourably accepted in France as well, but not in Britain since the government there was unwilling to look into his case. Ajudanbashi specifically objected to the role that
John McNeill, the British ambassador in Iran, was playing. In Mohammad Shah's opinion, McNeill was openly interfering in Iranian affairs and making irrational allegations and demands. The primary task of Ajudanbashi was to negotiate the restoration of diplomatic ties with the British government (which McNeill had damaged in anger at their refusal of Iran to abide by his demands), the removal of British troops from the
Kharg Island, and the selection of a new ambassador to take McNeill's position. Additionally, Ajudanbashi carried a friendly and optimistic letter written by Mohammad Shah to the newly ascended
Queen Victoria (). Due to the unbending stance taken by the British foreign secretary
Lord Palmerston in regards to the demands made towards the Iranian government, Ajudanbashi was unable to make his government's demands heard—let alone met—by British government officials. Instead, Ajudanbashi tried writing to parliamentarians and foreign diplomats, but those efforts also were unsuccessful. He ultimately departed England in the middle of July 1839. On his way back to Iran, Ajudanbashi had visited France again, where he managed to re-establish relations between the two countries, which had been practically stale since the death of the French diplomat and general
Claude Mathieu de Gardane in 1818. When Ajudanbashi returned to Iran, he learned that Palmerston's conditions had been reluctantly accepted by the prime minister
Haji Mirza Aqasi, who had received the approval of Mohammad Shah. == Governor of Fars ==
