XIV.--But the enemy, destitute of all honour, only waited a time and opportunity for fraud and treachery. And after an interval of some days, when our men were careless and negligent, on a sudden, at noon, when some were dispersed, and others indulging themselves in rest on the very works, after the fatigue of the day, and their arms were all laid by and covered up, they sallied out from the gates, and, the wind being high and favourable to them, they set fire to our works; and the wind spread it in such a manner that, in the same instant, the agger, plutei, testudo, tower, and engines all caught the flames and were consumed before we could conceive how it had occurred. Our men, alarmed at such an unexpected turn of fortune, lay hold on such arms as they could find. Some rush from the camp; an attack is made on the enemy: but they were prevented, by arrows and engines from the walls, from pursuing them when they fled. They retired to their walls, and there, without fear, set the musculus and brick tower on fire. Thus, by the perfidy of the enemy and the violence of the storm, the labour of many months was destroyed in a moment. The Massilians made the same attempt the next day, having got such another storm. They sallied out against the other tower and agger, and fought with more confidence. But as our men had on the former occasion given up all thoughts of a contest, so, warned by the event of the preceding day, they had made every preparation for a defence. Accordingly, they slew several, and forced the rest to retreat into the town without effecting their design.
