More formidable foes than the peasants had yet met were approaching La Vendee.

Mayence had surrendered to the allies, and the garrison there, which was a large one, composed of veteran troops, was allowed to march away, on each man taking an oath that he would not again serve on the frontier.
Outside France there was no idea of the desperate struggle that was going on in La Vendee.

Had it been known, in England, that it needed but little aid for Brittany and La Vendee to successfully oppose the efforts of the Republic, men, money, arms, and ammunition would no doubt have been sent; but unfortunately the leaders of the insurrection, occupied as they were with the efforts they were making, had taken no steps to send a statement of the real facts of the case to the English government.

The ports were all in the hands of the Republicans and, although in Paris public attention was concentrated on the struggle, the British government was very badly informed as to what was passing there.

Had the allies been aware of it, the terms granted to the garrison at Mayence would have been very different; and they would either have been held as prisoners, or been compelled to take the oath that they would, in future, not serve the Republic in any way, in arms.
As it was, they were free to act in France, and were already on the march towards La Vendee.
