During his illness, which only lasted a week, he made in his will a new acknowledgment of his son, naming his executors M. de Barriere, intendant of the province, and the sieur Vialet, treasurer of France, desiring them to bring the lawsuit to an end. His last words were for his wife and child; his only regret that he had not been able to terminate this affair. He died on the 31st of January 1659.

The maternal tenderness of the countess did not need stimulating by the injunctions of her husband, and she took up the suit with energy. The ladies de Ventadour and du Lude obtained by default letters of administration as heiresses without liability, which were granted out of the Chatelet. At the same time they appealed against the judgment of the lieutenant-general of the Bourbonnais, giving the tutelage of the young count to the countess his mother, and his guardianship to sieur de Bompre. The countess, on her side, interpleaded an appeal against the granting of letters of administration without liability, and did all in her power to bring back the case to the Tournelle. The other ladies carried their appeal to the high court, pleading that they were not parties to the lawsuit in the Tournelle.

It would serve no purpose to follow the obscure labyrinth of legal procedure of that period, and to recite all the marches and countermarches which legal subtlety suggested to the litigants. At the end of three years, on the 9th of April 1661, the countess obtained a judgment by which the king in person:

"Assuming to his own decision the civil suit pending at the
Tournelle, as well as the appeals pled by both parties, and the
last petition of Mesdames du Lude and de Ventadour, sends back
the whole case to the three assembled chambers of the States
General, to be by them decided on its merits either jointly or
separately, as they may deem fit."

The countess thus returned to her first battlefield. Legal science produced an immense quantity of manuscript, barristers and attorneys greatly distinguishing themselves in their calling. After an interminable hearing, and pleadings longer and more complicated than ever, which however did not bamboozle the court, judgment was pronounced in Conformity with the summing up of the attorney-general, thus—

"That passing over the petition of Mesdames Marie de la Guiche and Eleonore de Bouille, on the grounds," etc. etc.;

"Evidence taken," etc.;

"Appeals, judgments annulled," etc.;

"With regard to the petition of the late Claude de la Guiche and Suzanne de Longaunay, dated 12th August 1658,"

"Ordered,
