Context

“Marius fought unprotected. He made himself a target. He stood with more than half his body above the breastworks. There is no more violent prodigal than the avaricious man who takes the bit in his teeth; there is no man more terrible in action than a dreamer. Marius was formidable and pensive. In battle he was as in a dream. One would have pronounced him a phantom engaged in firing a gun. The insurgents’ cartridges were giving out; but not their sarcasms.” source
