The King my husband had received intelligence, the evening before, of the expected arrival of M. de Cornusson, and was desirous of preventing the junction, for which purpose he resolved to attack him and the Marshal separately. As he had been lately joined by M. de La Rochefoucauld, with a corps of cavalry consisting of eight hundred men, formed from the nobility of Saintonge, he found himself sufficiently strong to undertake such a plan. He, therefore, set out before break of day to make his attack as they crossed the river. But his intelligence did not prove to be correct, for De Cornusson passed it the evening before. My husband, being thus disappointed in his design, returned to Nerac, and entered at one gate just as Marechal de Biron drew up his troops before the other. There fell so heavy a rain at that moment that the musketry was of no use. The King my husband, however, threw a body of his troops into a vineyard to stop the Marshal’s progress, not being able to do more on account of the unfavourableness of the weather.
In the meantime, the Marshal continued with his troops drawn up in order of battle, permitting only two or three of his men to advance, who challenged a like number to break lances in honour of their mistresses. The rest of the army kept their ground, to mask their artillery, which, being ready to play, they opened to the right and left, and fired seven or eight shots upon the town, one of which struck the palace. The Marshal, having done this, marched off, despatching a trumpeter to me with his excuse. He acquainted me that, had I been alone, he would on no account have fired on the town; but the terms of neutrality for the town, agreed upon by the King, were, as I well knew, in case the King my husband should not be found in it, and, if otherwise, they were void. Besides which, his orders were to attack the King my husband wherever he should find him.
I must acknowledge on every other occasion the Marshal showed me the greatest respect, and appeared to be much my friend. During the war my letters have frequently fallen into his hands, when he as constantly forwarded them to me unopened. And whenever my people have happened to be taken prisoners by his army, they were always well treated as soon as they mentioned to whom they belonged.
I answered his message by the trumpeter, saying that I well knew what he had done was strictly agreeable to the convention made and the orders he had received, but that a gallant officer like him would know how to do his duty without giving his friends cause of offence; that he might have permitted me the enjoyment of the King my husband’s company in Nerac for three days, adding, that he could not attack him, in my presence, without attacking me; and concluding that, certainly, I was greatly offended by his conduct, and would take the first opportunity of making my complaint to the King my brother.
