Battle of Beas River

The battle of Beas River was a battle between Chagatai Khanate army and the Mamluk sultanate in 1285. Ghiyas ud din Balban arranged a military defense line across Beas River as part of his "blood and iron" fortification chain strategy at Multan and Lahore as a countermeasure against the Chagatai Khanate invasion. Balban managed to repulse the invasion. However, his son Muhammad Khan was slain in battle.
