His plan was by spreading false rumours and making feigned marches to draw the Camisards into a trap in which they, in their turn, would be caught.

This was the less difficult to accomplish as their latest great victory had made Cavalier over confident both in himself and his men.
In fact, since the incident connected with the naval officers the troops of Cavalier had increased enormously in numbers, everyone desiring to serve under so brave a chief, so that he had now under him over one thousand infantry and two hundred cavalry; they were furnished, besides, just like regular troops, with a bugler for the cavalry, and eight drums and a fife for the infantry.
The marechal felt sure that his departure would be the signal for some expedition into the level country under Cavalier, so it was given out that he had left for Montpellier, and had sent forward some of his baggage-waggons to that place.

On April 15th he was informed that Cavalier, deceived by the false news, had set out on the 16th April, intending to pass the night at Caveyrac, a small town about a league from Nimes, that he might be ready next day to make a descent on La Vannage.

This news was brought to M.de Montrevel by a village priest called Verrien, who had in his pay vigilant and faithful spies in whom he had every confidence.
Montrevel accordingly ordered the commandant of Lunel, M.de Grandval, to set out the next day, very early in the morning, with the Charolais regiment and five companies of the Fimarcon and Saint-Sernin dragoons, and to repair to the heights of Boissieres, where instructions would await him.

Sandricourt, governor of Nimes, was at the same time directed to withdraw as many men as possible from the garrison, both Swiss and dragoons, and send them by night towards Saint-Come and Clarensac; lastly, he himself set out, as he had said, but instead of going on to Montpellier, he stopped at Sommieres, whence he could observe the movements of Cavalier.
Cavalier, as M.de Montrevel already knew, was to sleep on the 15th at Caveyrac.
