The tactic that Remus decided to employ was certainly a risky one. If it failed, it would be disastrous for him.
However just like Alexander said, they needed to take some risks to win this campaign.
So once it was confirmed that the enemy had no cavalry, the young man decided to roll the die.
As for the consequences if he failed, well there was no need for Scorpyo to punish him.
Remus intended to go down with his 'ship'. That was also another reason why he was leading from the front and putting himself in so much risk.
And as of right now, that gamble seemed to be paying off, with Scorpyo making considering progress at driving the enemy formation back and making the lines crack and buckle.
And aside from the legionaries's brave assaults, a large part of that success was also due to how Lord Macht had arranged his troops.
