nterval 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.

XV.--Trebonius began to provide and repair what had been destroyed, with
much greater zeal on the part of the soldiers; for when they saw that
their extraordinary pains and preparations had an unfortunate issue,
they were fired with indignation that, in consequence of the impious
violation of the truce, their valour should be held in derision. There
was no place left them from which the materials for their mound could be
fetched, in consequence of all the timber, far and wide, in the
territories of the Massilians, having been cut down and carried away;
they began therefore to make an agger of a new construction, never heard
of before, of two walls of brick, each six feet thick, and to lay floors
over them of almost the same breadth with the agger, made of timber. But
wherever the space between the walls, or the weakness of the timber,
seemed to require it, pillars were placed underneath and traversed beams
laid on to strengthen the work, and the space which was floored was
c
