It seems to me that you've changed the subject from French officers being given an officer's commission in the English Navy/Army to did foreign troops serve a long side English

I was responding to your question: "Who, other than Smith, in the English army or navy is known to have employed the skills of a French engineer in the field? " It is clear that a number of French engineer officers were taken into British pay and served in the field.

I quoted this article to support my earlier statement that the practice of engaging French engineer officers in British service was well established before Smith at Acre (which you had questioned) - the fact that they were not commissioned in the British regular armies was not the issue - I don't believe that Phelippeaux was either. It is clear that French engineers were used before Smith at Acre.
