Bhagavad-gita As It Is Lectures

Duryodhana thought that for, continually for thirteen years Pāṇḍavas were banished, so they could not gather any good amount of soldiers.

Lecture on BG 1.16-19 -- London, July 16, 1973:

So all these kings on the side of the Pāṇḍavas, they were relatives, so they joined. So when they blew their different types of conchshell, then the other side were trembled, "Oh, they have gathered so much strength." Because Duryodhana thought that for, continually for thirteen years Pāṇḍavas were banished, so they could not gather any good amount of soldiers. But when they saw that so many kings from different parts of the world have joined them, so they became frightened. That is described in the next verse, sa ghoṣo dhārtarāṣṭrāṇāṁ hṛdayāni vyadārayat. They are just like heart-broken: "What is this? They have gathered so much great, great fighters." Nabhaś ca pṛthivīṁ caiva tumulo 'bhyanunādayan.
