The Delhi Sultans — Social Studies STD 7 — Question

Chieftains sometimes fortified themselves in mountains, in rocky, uneven and rugged places as well as in bamboo groves. In India the bamboo is not hollow; it is big. Its several parts are so intertwined that even fire cannot affect them, and they are on the whole very strong. The chieftains live in these forests which serve them as ramparts, inside which are their cattle and their crops. There is also water for them within, that is, rain water which collects there. Hence they cannot be subdued except by powerful armies, who entering these forests, cut down the bamboos with specially prepared instruments.”
