Madra king Shalya, came with an Akshouhini of troops to join the army of Pandavas, since his nephews viz the twins Nakula and Sahadeva were none other than the youngest Pandavas. His troops marched slowly on every day from Madra (Punjab province of Pakistan) to Upaplavya (somewhere on the border of Rajasthan and Haryana), the Matsya city, where the Pandavas were camped. When his army reached Kurujangala (the kingdom of the Pandavas, the modern-day Haryana), Duryodhana's men intercepted the army. They, without revealing their identity, received Shalya and his men, made tents for them and refreshed them with all comforts. The Madra soldiers also received payment from Duryodhana's officers for taking part in the Kurukshetra War. Shalya became indebted to battle for the sake of Duryodhana, by the time he learned the truth. (5,8).
