As a minister Balban was not softhearted. When he became the Sultan, he followed the policy of blood and iron, which means that his killings became even more sanguinary. His sphere of operations was, however, confined to the Ganga-Jamuna doab and Avadh, Katehar and Mewat. In Katehar large sections of the male population were massacred and, according to Barani, in villages and jungles heaps of human corpses were left rotting. During his expedition to Bengal, ‘on either side of the principal bazar (of Lakhnauti) in a street two miles in length, a row of stakes was set up and the adherents of Tughril were impaled upon them.’

What It Means

When he became the Sultan, he followed the policy of blood and iron, which means that his killings became even more sanguinary. His sphere of operations was, however, confined to the Ganga-Jamuna doab and Avadh, Katehar and Mewat.

During his expedition to Bengal, ‘on either side of the principal bazar (of Lakhnauti) in a street two miles in length, a row of stakes was set up and the adherents of Tughril were impaled upon them.’" in the context of "Lal, K. S. (1990). Indian muslims: Who are they." to mean that wisdom is timeless.
