Tarbiyat Khan, the chief of artillery, worked hard in running lanes and raising gun-platforms. In a short time five towers of the fort were battered down to half their heights. A mine, large enough for three armed men to walk abreast erect, was gradually carried under the tower and outer breast-work of the fort-gate. It was a most elaborate structure, with a chamber for 20 soldiers furnished with windows on both sides for admitting air and light and musketry-holes for firing at the ramparts.
