The informant, whose authority may be depended on, adds that a squadron from Brest was expected to join them. It was supposed that the whole armament would be directed against Portugal; and this supposition was not weakened by a report which was given out industriously that the object of the intended expedition was to make a landing on the coast of Barbary, in order to force the Emperor of Morocco to shut his ports against the English. The ships from Ferrol have the French and Spanish colours united in the same flag. It was understood that the ships now arming in Cadiz were to be commanded by French officers. They were victualled only for a very short voyage. Respecting the danger to which this capital would be exposed by a _coup-de-main_, which might be attempted in spite of the batteries at the entrance of the river, as well as the possibility of effecting a landing a few miles off Cascaes, your lordship has at hand the means of information so much superior to any which I could presume to offer, or collect from professional persons here, that I shall only presume to solicit your lordship's attention to the consideration of this subject, and to the necessity which may arise out of it, for employing a naval force upon this station. Don Rodrigo has informed me that the three Portuguese ships of the line, which I mentioned to your lordship as preparing for service, will be ready within three weeks to form a junction with any force which his Majesty might be pleased to detach, for the defence of Portugal; and that two more would be prepared to follow them within a short time after. It appears by a letter from Viana, that the master of an English vessel, who had been captured on the 10th ultimo by Le Telegraph privateer, and carried into Corunna on the 23rd, had found there two large French frigates, which had arrived immediately before him in eight days from Cherbourg, laden with some ammunition, and destined (as they reported) for Cadiz. The master of Le Telegraph had avoided putting into any of his own ports from the apprehension of being detained, as it was reported that other privateers had been stopped, and stripped of their men, on account of a secret expedition which was fitting out in the French ports. I have the honour to be, &c. J.H. FRERE. The Right Honourable Lord Hawkesbury, &c. &c. &c. No. 3. Intelligence arrived from General O'Hara, at Gibraltar.
