While the Duc d'Angouleme had been staying at Nimes, General Gilly had applied for a command in that prince's army, but in spite of all his efforts obtained nothing; so immediately after the dinner at which he was insulted he had withdrawn to Avernede, his place in the country. He was awoke in the night of the 5th-6th April by a courier from General Ambert, who sent to offer him the command of the 2nd Subdivision. On the 6th, General Gilly went to Nimes, and sent in his acceptance, whereby the departments of the Gard, the Lozere, and Ardeche passed under his authority.
Next day General Gilly received further despatches from General Ambert, from which he learned that it was the general's intention, in order to avoid the danger of a civil war, to separate the Duc d'Angouleme's army from the departments which sympathised with the royal cause; he had therefore decided to make Pont-Saint-Esprit a military post, and had ordered the l0th Regiment of mounted chasseurs, the 13th artillery, and a battalion of infantry to move towards this point by forced marches. These troops were commanded by Colonel Saint-Laurent, but General Ambert was anxious that if it could be done without danger, General Gilly should leave Nimes, taking with him part of the 63rd Regiment, and joining the other forces under the command of Colonel Saint-Laurent, should assume the chief command. As the city was quite tranquil, General Gilly did not hesitate to obey this order: he set out from Nimes on the 7th, passed the night at Uzes, and finding that town abandoned by the magistrates, declared it in a state of siege, lest disturbances should arise in the absence of authority. Having placed M. de Bresson in command, a retired chief of battalion who was born in Uzes, and who usually lived there, he continued his march on the morning of the 8th.
Beyond the village of Conans, General Gilly met an orderly sent to him by Colonel Saint-Laurent to inform him that he, the colonel, had occupied Pont Saint-Esprit, and that the Duc d'Angouleme, finding himself thus caught between two fires, had just sent General d'Aultanne, chief of staff in the royal army, to him, to enter into negotiations for a surrender. Upon this, General Gilly quickened his advance, and on reaching Pont-Saint-Esprit found General d'Aultanne and Colonel Saint-Laurent conferring together at the Hotel de la Poste.
As Colonel Saint-Laurent had received his instructions directly from the commander-in-chief, several points relating to the capitulation had already been agreed upon; of these General Gilly slightly altered some, and approved of the others, and the same day the following convention was signed:
"Convention concluded between General Gilly and Baron de Damas "S.A.R. Mgr. le Duc d'Angouleme, Commanderin-Chief of the royal army in the South, and Baron de Gilly, General of Division and Commander-in-Chief of the first corps of the Imperial Army, being most anxiously desirous to prevent any further effusion of French blood, have given plenary powers to arrange the terms of a convention to S.A.R.
