Pradyumna: "Translation: Our strength is immeasurable, and we are perfectly protected by Grandfather Bhīṣma, whereas the strength of the Pāṇḍavas, carefully protected by Bhīma, is limited." (BG 1.10)
Prabhupāda: So Duryodhana is very proud of his strength, military strength, because he was empowered, he could gather. And over and above that, Bhīṣma is the commander-in-chief. He is giving protection. And on the other side, the Pāṇḍavas, they are not empowered. Somehow or other, they gathered some soldiers from relatives. Therefore their strength was limited in consideration of the other party. And that is, being protected by Bhīma. Duryodhana always considered Bhīma as a fool. Therefore he is very much confident that "Our side is being protected by Bhīṣma, and the other side, although Bhīma is very strong, but he has no brain very much." So he was very hopeful of victory.
