newly acquired province and administered it among Sher Ali Khan, who ruled Ghazni, and Jalal al-Din Khan, who ruled Zamindawar and Grishk. Haidar Khan also followed his uncles reforms in an attempt to raise revenue, which included auctioning irrigation water to the highest bidders during summer time, as well as the issuing of a new currency periodically throughout the year of new copper coins. Maimana Campaign (1857) On 15 January 1857, Afzal Khan, alongside other sardars rested and enjoyed their mid-day meal.
