A letter is transcribed in a 1998 Clan MacKenzie listserve posting, source noted as "Colonies C/8a/58, fo 86" (note that the following dates are probably in the Gregorian calender then used by the French government and navy);
Le 14 aout 1747, le gouverneur de Martinique, M. de Caylus, ecrit au ministre, en duplicata, une lettre chiffree (dont la transcription par les bureaux du ministere est donnee en interlignes) :
"J'ai eu l'honneur de vous rendre compte, par ma lettre du 12 juillet dernier par la Hollande [lettre non conservee], qu'un corsaire de cette colonie avait pris un vaisseau sur lequel on avait embarque 160 Ecossais qui devaient, par ordre du roi, etre vendus comme esclaves aux Isles sous le Vent, pour avoir pris les armes contre le prince Edouard. [ I think he meant "pour le prince"? ]
"Deux capitaines, huit autres, tant sergents que soldats, qui etaient de ce nombre, m'ayant demande de passer en France par ces batiments qui sortent sans convoi, je le leur ai permis et je vous en rends compte afin que vous ayez la bonte de donner, a leur arrivee dans les ports, les ordres que vous jugerez convenables.
"Su r les representations qu'ils m'ont faites, j'ai donne des ordres aux capitaines pour les passer comme prisonniers de guerre et je vous ecris ainsi dans la crainte que, cette lettre tombant entre les mains des Anglais, ces malheureux ne fussent reconnus et maltraites."

On the 14 August, 1747, the Governor of Martinique, M. de Caylus, wrote to the Minister, in duplicate, a letter Encrypted (Whose transcription by the offices of the ministry is given in interlining)
"I had the honour to report to you in my letter of 12 July by the Hollande [letter not kept, likely refers to a ship called "la Hollande", rather than sent through the land of Holland] that a corsaire [privateer] of this colony had taken a vessel which had 160 Scots on board, who by Orders of the King were to have been sold as slaves in the Windward Isles, for having taken up arms for the Prince Edward.
"Two captains and eight others, some of those sergeants, some soldiers, asked me to arrange their passing to France that these batiments [ ships, not necessarily fighters, but with big or medium size tonnage as opposed to small ships ] can go without convoy, I allowed them to do so, and I and I tell you this so that you be kind enough, when they arrive in port, to give such orders as you deem appropriate.
"On the representations made by them to me, I have given orders to the captains to pass as prisoners of war and I thus write to you in the fear that, should this letter fall into the hands of the English, these unfortunates be recognized and mistreated."
