Dost Mohammad's Campaign to Jalalabad (1834) took place in Early 1834, prior to the summer invasion of Shah Shuja Durrani in Kandahar.

The Dil brothers, who ruled the Principality of Qandahar, pleaded for aid from Dost Mohammad Khan as fears of Shah Shuja Durrani invading Kandahar and restoring himself to the throne were looming.

As a result, Dost Mohammad decided to come to their aid, but took advantage of such by increasing his influence with concessions from the Kandahar Sardars.

However, before doing so, Dost Mohammad aimed to secure a strategic area around Jalalabad to hold of if the Sikh Empire or a detachment of Shah Shuja or his allies were sent.
