Cato the Younger

And indeed it was currently said among those citizens who still retained their good sense, that the consular power must not be suffered to become altogether overweening and oppressive by the union of the influence of Pompey and Crassus, but that one or the other of these men must be deprived of it. So they joined the party of Domitius, inciting and encouraging him to persist in his opposition; for many, they said, who now held their peace through fear, would help him when it came to voting.

This was precisely what the partisans of Pompey feared, and so they set an ambush for Domitius as he was going down at early morning by torchlight into the Campus Martius. First of all the torch-bearer who stood in front of Domitius was smitten, fell, and died; and after him the rest of the party were presently wounded, and all took to flight except Cato and Domitius.
