Part of the reason why Ves was so persuasive was because he truly believed in his words. He was not putting up an act, nor did he try to channel Vulcan by putting on a mask.
He was too tired of that. His stunt with Blinky caused him to become mentally and physically drained. In fact, he was in an uncommonly sober and calm mood after his emotions became dull due to his current state.
If he retained a lot more energy, then he might have been inclined to order his troops to keep pushing their advantage and to pay back the dwarves tenfold for the losses they inflicted on the Larkinson Clan!
As it was, Ves did not see any purpose to that. Destroying all of enemy mechs would yield nothing except for useless salvage and satisfying some pointless urges.
