As part of the scheme the French considered trying to start a Jacobite rebellion, as they had in 1745, by sending the heir apparent of the Jacobite movement Charles Edward Stuart with or ahead of the invading forces.
A secret meeting was arranged with Charles Stuart in Paris in February 1759, but it went badly.
Charles turned up late and drunk, and proved surly and uncooperative.
Convinced that the Jacobites were of little material help, Choiseul dropped them from the plan.
  From then on, any French landing would have to be entirely accomplished by French troops.
He did however consider sending Bonnie Prince Charles to Ireland where he could be declared King of Ireland and lead a rebellion.
Eventually the French decided to try to recruit Jacobite supporters without involving Charles directly in the operation – as he was considered a potential liability.

France also sought support from Denmark and Russia to provide troops and naval stores for the expedition, but both declined to participate.
Sweden initially agreed to take part in the scheme by sending an invasion force to Scotland, but later backed out of this arrangement.
The Dutch Republic, traditionally a British ally but neutral at the time, was deeply alarmed by the French actions, and demanded assurances that the French were not planning to place the pretender Stuart on the British throne, an action they believed would threaten their own security.
The French ambassador assured them they were not.
