Cock up or conspiracy?

Pepy's diary suggests a cock up rather than conspiracy (at his level at least).

I find the Court full of great apprehensions of the French, who have certainly shipped landsmen, great numbers, at Brest; and most of our people here guess his design for Ireland. We have orders to send all the ships we can possible to the Downes. God have mercy on us! for we can send forth no ships without men, nor will men go without money, every day bringing us news of new mutinies among the seamen; so that our condition is like to be very miserable. Thence to Westminster Hall, and there met all the Houblons, who do laugh at this discourse of the French, and say they are verily of opinion it is nothing but to send to their plantation in the West Indys, and that we at Court do blow up a design of invading us, only to make the Parliament make more haste in the money matters, and perhaps it may be so, but I do not believe we have any such plot in our heads.
