The British laid out the vast Peshawar Cantonment to the west of the city in 1868, and made the city its frontier headquarters. Additionally, several projects were initiated in Peshawar, including linkage of the city by railway to the rest of British India and renovation of the Mohabbat Khan mosque that had been desecrated by the Sikhs. British suzerainty over regions west of Peshawar was cemented in 1893 by Sir Mortimer Durand, foreign secretary of the British Indian government, who collaboratively demarcated the border between British controlled territories in India and Afghanistan.
