His stand, in his own words, and the retreat that followed
The Seir Mutaqherin records that as the battle at Plassey went on, "Mohon-lal, who had advanced with Mir-meden, was closely engaged with the enemy; his cannon was served with effect; and his infantry having availed themselves of some covers and other grounds, were pouring a quantity of bullets in the enemy's ranks. It was at this moment he received the order of falling back, and of retreating."
His answer is given as direct speech: "He answered: 'That this was not a time to retreat; that the action was so far advanced, that whatever might happen, would happen now; and that should he turn his head, to march back to camp, his people would disperse, and perhaps abandon themselves to an open flight.'"
Siraj-ud-Daula, intimidated by Mir Jafar's coldness, "sent repeated orders, with pressing messages, to Mohon-lal; who at last obeyed, and retreated from the post to which he had advanced." The text states plainly what followed: "This retreat of Mohon-lal's made a full impression on his troops. The sight of their General's retreat damped their courage..".
