According to the original plan, it would take at least 5 days to attack Jaisalmer. Therefore, all related arrangements, especially logistics support, were prepared for an intense assault lasting 5 days. However, on the night of the 21st, when the 17th Armored Division advanced to the outskirts of the city, the Fan Army guarding Jaisalmer raised the white flag. By the next morning, the vanguard of the 17th Armored Division had entered Jaisalmer.
In total, over 60,000 Fan Army troops surrendered and laid down their arms.
In other words, apart from those eliminated in previous battles and those dispatched to Sheo, nearly the entire Fan Army guarding Jaisalmer surrendered.
Actually, this is not surprising.
