Duryodhana manages to win the army of king Shalya, the maternal uncle of the Pandavas. Duryodhana intercepts Shalya’s army as it comes to Kurukshetra and offers hospitality; Shalya accepts thinking Yudhishthira had made the offer. After Shalya has enjoyed Duryodhana’s comforts, Duryodhana reveals the treachery, and indicates that Shalya is now indebted to him. He uses this indebtedness to extract Shalya’s army and support. Duryodhana wanted Shalya mainly so that Karna would have an equivalent charioteer to Arjuna’s Krishna.
