The onward thrust into India would be launched from Kabul or Kandahar. Duhamel preferred Kabul as it offered the quickest route, via the Khyber Pass, to the Indian cities of Lahore and Delhi, where he hoped that large numbers of rebels would rise to join his forces. It also offered the best prospects of loot and territorial gains for his Afghan allies. This march from Kabul would be made via Jalalabad (Afghanistan), through the British Indian cities of Peshawar and Attock Khurd. Duhamel had hopes that the Muslim tribal population of this region would rebel and assist the expedition. Duhamel had two alternatives for a Kandahar route: running through Quetta, Dadu and Shikarpur or via Ghazna and Dera Ismail Khan. Duhamel noted that the Kandahar route would be the same as that taken by the 1839 British invasion of Afghanistan, but in reverse. There was little detailed logistical planning. For example he assumed that the Russian forces could consistently cover a day across Persia and Afghanistan.
