I remember learning about the Vietnam war in history class, i thought the exact same thing, the amount of North Vietnamese soldiers was a measly 461,000 whereas the Americans and their allies had over 1 million troops (over twice as much) however, the North Vietnamese won! And moreover, with much less casualties. This led me to believe they definitely had some supernatural abilities or they were just extraordinarily smart with using tactics such as guerrilla fighting etc.

This also reminds me of the historic Khalsa battles such as the battle of Mukatsar in which Maharaj Sri Guru Gobind Singh Jee only had an army of around 40 (Chaalee Mukte along with the panj piaare and their two Sahibzaade - i think), thus roughly an army of 48. Yet, Wazir Khan had an army of well over 100,000 yet around It was said in the Zafarnama that each Sikh probably killed 100's yet 11 Sikhs, and Guru Gobind Singh jee Maharaj remained physically alive - thus, the Mughal forces were not successful in their aim
