When was the dagger vs the pugio used

[stevesarak]

I must disagree with you Ambrosius

I don't think so that soldiers had a chance to change their weapons in the middle of a combat.

What would you do?
If two lines rushed each other, and you were pressed up against the enemy with your men pressing up behind you, so tight that you could barely move, and you stood there, staring into the eyes of your enemy, who shouts back insults into your face about your cattle or farm, then starts yelling insults about your cohort, how his seven ugly, bearded sister could whip any of your men, your temper might blow and you might try withdrawing your dagger for those sweet neck shots.
