I can't understand why Kauravas had to bring their entire star decked warriors to attack Virata, sure they are just helping their allies Trigarta's as their commander-in-chief had been slain, so they are attacking someone who's already weaker still they brought senior warriors like Bhisma,Drona,Kripa,Ashwattama unnecessarily.
Given that Pandavas subjugated all the kingdoms by sending each brothers on each direction , and Karna too subjugated all the kingdoms by himself after the Gandharava defeat.
So I can't understand the reason behind these much warriors participating for a mere Virata attack, aren't they on different level to participate on such small tasks .
And the Virata war was completely different,there were no use of celestial weapons,it just looks like raw skirmish with ordinary arrows, until Arjuna alone uses one celestial weapon in the end to finish the war, which completely contradicts the war scenes from Kuruschestra.
Hearing these words of Susarman, Karna addressed the king, saying, 'Susarman hath spoken well; the opportunity is favourable and promises to be profitable to us. Therefore, if it pleases thee, O sinless one, let us, drawing up our forces in battle array and marshalling them in divisions, speedily set out. Or, let the expedition be managed as Saradwata's son Kripa, the preceptor Drona, and the wise and aged grandsire of the Kurus may think. Consulting with each other, let us, O lord of earth, speedily set out to attain our end. What business have we with the sons of Pandu, destitute as they are of wealth, might, and prowess? They have either disappeared for good or have gone to the abode of Yama? We will, O king, repair without anxiety to Virata's city, and plunder his cattle and other wealth of diverse kinds.'
Here it's clear Kauravas didn't plan Virata war to find the Pandavas, they just wanted to help their allies.
