to be a dancing girl while his three nephews were castrated. As an excuse for the treachery, Sher Shah claimed it as a revenge for enslavement of Muslim women and that he had once, when seriously ill, pledged to wipe out the Rajputs of Raisen. Conquest of Marwar In 1543, Sher Shah Suri with a force of 80,000 cavalry set out against Maldeo Rathore, the Rajput king of Marwar. Maldeo Rathore with an army of 50,000 cavalry advanced to face Sher Shah's army. Instead of marching to the enemy's capital Sher Shah halted in the village of Sammel in the pargana of Jaitaran, ninety kilometres east of Jodhpur. After one month of skirmishing, Sher Shah's position became critical owing to the difficulties of food supplies for his huge army. To resolve this situation, Sher Shah resorted to a cunning ploy. One evening, he dropped forged letters near the Maldeo's camp in such a way that they were sure to be intercepted. These letters indicated, falsely, that some of Maldeo's army commanders were promising assistance to Sher Shah. This caused great consternation to Maldeo, who immediately (and wrongly) suspected his commanders of disloyalty. Maldeo left for Jodhpur with his own men, abandoning his commanders to their fate. After that Maldeo's innocent generals Jaita and Kumpa fought with just a few thousand men against an enemy force of 80,000 men and cannons. In the ensuing battle of Sammel (also known as battle of Giri Sumel), Sher Shah emerged victorious, but several of his generals lost their lives and his army suffered heavy losses. Sher Shah is said to have commented that "for a few grains of bajra (millet, which is the main crop of barren Marwar) I almost lost the entire kingdom of Hindustan." According to Mughal historian Badauni, Sher Shah's use of elephant troops helped him defeat the Rajput army. After this victory, Sher Shah's general Khawas Khan Marwat took possession of Jodhpur and occupied the territory of Marwar from Ajmer to Mount Abu in 1544. Government and administration The system of tri-metalism which came to characterise Mughal coinage was introduced by Sher Shah. While the term rūpya had previously been used as a generic term for any silver coin, during his rule the term rūpee came to be used as the name for a silver coin of a standard weight of 178 grains, which was the precursor of the modern
