As a diplomat he worked for Françoise de Bourbon, Duchess of Bouillon,[3] and was an informant for Francis Walsingham, reporting on English visitors at Rouen, and declared that he was as sure and constant in Walsingham's service 'as a diamond is hard'.[4] He sent gifts of dried fruit, apples, and pears to Ursula St Barbe and Lettice Knollys, the wives of Walsingham and Robert Dudley, 1st Earl of Leicester.[5]
He came to London and met Elizabeth I in 1584 and 1588. With Oudard de Jolitemps, he brought jewels from the Duchess of Bouillon in August 1584, visited the Earl of Huntingdon in York in September,[6] and in October Francis Walsingham sent him a diamond ring. The Duchess had hoped they would be able to secure places for her nieces Louise and Elisabeth of Nassau in the household of Elizabeth I. They were left orphans at the assassination of William the Silent.[7][8]
François and his wife, Jehanne du Mouchet, and family came to Rye in July 1585 and were listed as Protestant refugees in London in January 1586.[9]
In 1588, Elizabeth gave him a jewel and her portrait, according to an inscription on a painting belonging to his descendants.[10] Leaving his wife in London, he travelled to Edinburgh in March 1589 to raise an army of 3000 soldiers for Henri of Navarre and work on the unsuccessful negotiations for the marriage of James VI of Scotland to Catherine de Bourbon, the sister of Henri of Navarre.
James was advised of Civille's mission by Henri's letter of 23 December 1588. Civille arrived in Edinburgh on 10 March 1589 and had his first audience on 15 March. David Moysie wrote only that Civille was a "packet bearer" from Navarre who came for troops.[11]
An English observer at the Scottish court Thomas Fowler wrote that Civille and Jérôme Groslot, Sieur de l’Isle encouraged Edinburgh merchants who dealt with France to support the Navarre marriage.[12] However, James married Anne of Denmark instead.[13] A cipher key in the Hawthornden manuscripts relates to their missions.[14]
Civille mentioned in a letter from Wemyss that the Earl of Huntingdon was his 'old and gracious master'. Civille was given 1,200 merks on 11 September 1589[15] and left Scotland from Dundee accompanied by James Colville of Easter Wemyss and 1,500 Scottish troops.[16] Adverse winds drove them back into the Firth of Forth.[17] According to David Moysie the 1,500 soldiers had left Scotland in June 1589 [18] Civille wrote to James VI from Dieppe on 22 August 1592.[19]
In January 1598 Henri IV ordered Civille as "Commissaire Ordinaire des Guerres" to take command of troops at Saumur.[20]
