First cadet-gentilhomme, and then Captain in the grenadiers-a-cheval of Brandenburgh, killed at the siege of Tournai, 1709. [This is word-for-word identical in Lart
18 and
19[C-D, III, 386]. I bet that Lart just copied. What a naughty man.]
Lart and CD conflate Francois and Henri into one person. I follow BBB here.
15[BBB]: “The first of the Boileau family to leave France were the two eldest surviving sons of Jacques ii, Henri iii and Jean-Louis i. They were in one of the 'Compagnies des Cadets' established in France for the sons of Nobles or of former officers whose fortune was not equal to their birth, and to whom military service offered more opportunities than other vocations. They were trained in all the knowledge and drills necessary, and then placed in the subaltern ranks of the army. Among them were a large number of young Huguenots, and after the Revocation many of these escaped to Brandenburg. Some of the companies, including that at Besançon, where Henri and Jean-Louis were stationed, were near to the frontier, and so it was easy for a crowd of cadets to get over. The two young Boileaus did so on 7th December, 1685, and went to Brandenburg, where the Elector was making the Huguenots welcome, and especially those who were officers and soldiers.”
