The Deccan Sultanates and Vijayanagara were more relevant to world history in the 16th Century India. The wonders of Bijapur, Golconda and Hampi would put 16th CE Delhi to shame.
>The Mughal position was again fortified with a ditch and wagons linked by chains and the matchlockmen, placed in the front of the force, ‘broke the ranks of the pagan army with matchlocks and guns like their hearts’; they were black and covered with smoke. The Mughals had only about 12,000 troops at Kanua, whereas the Rajputs, allegedly, had 80,000 cavalry and 500 elephants
Digging the ditch during the battle is a typical and signature Persian war technique.
Not trying to be pedantic but the more correct word to use here is probably trench. The trench is called Khandaq in Persian and Arabic, the latter most probably a borrowed word from the former.
The main idea is to pre-emptively dig a trench beforeva battle just enough to prevent the enemies cavalry horses from jumping across.
It's succesfully used by early Islamic force against the much larger Meccan Quraish army including their allies during the famous Khandaq war in defending Yathrib (now Madinah) [1]. The idea was suggested by Salman al-Farisi, a Persian companian of Muhammad [2].
Fun facts, Mughals palace households were mainly speaking Persian language, and the Hindi/Urdu language is heavily influenced by the Persian moreso than Arab.

Imagine a similar description of conquest by, say, the Christian Spaniards in the Americas. The noble conquests of the brave Hernan Cortés, in similarly flowery language. Imagine the shouts of protest against... well, there is no nedd to imagine since those protests are commonplace.
The Islamic conquest and colonisation of the middle- and far-east is one of the more bloody episodes in history rife with all the vices for which western colonisers are constantly blamed. Slavery was and in some places still is commonplace but the same voices which proclaim the vices of the west are silent or point at the virtues of others who were and sometimes still are guilty of the same. Why is that?
