It is obvious that Virgil despises war and sees it as self destructive to all involved in it.

“Wars at an end, harsh centuries then will soften,
Ancient Fides and Vesta, Quirinus
With Brother Remus, will be lawgivers,
And grim with iron frames, the Gates of War
Will then be shut: inside, unholy Furor,
Squatting on cruel weapons, hands enchained
Behind him by a hundred links of bronze,
Will grind his teeth and howl with bloodied mouth.”

In this excerpt, Virgil implies that the gods and goddesses of order and faith will only return after the beast called War is restrained. The roots of civilization will crumble when war begins.

‘We’ll take their shields and put on their insignia!
Trickery, bravery: who asks, in war?
The enemy will arm us.’

In this excerpt, Coroebus plans a strategy to deceive the enemy by dressing like them and implies that truth is one of the first things to be eliminated in warfare. All players of war are so focused on destroying their foes that they may lose common sense. This is also called the fog of war.
