“By the same opportunity I have the honour to acquaint you that I have received a dispatch from the Arch-duke John, in which he mentions his most earnest desire, that the whole force under your command should go as soon as possible to the coast of Dalmatia, and particularly towards Zara, where he wishes that an attempt might be made by the British men of war, firing against that place, or in any other way, that might draw the attention of the enemy, and operate a diversion, giving at the same time a signal for the insurrection of the inhabitants to break out, who expect nothing else than the occasion; whilst our troops will make a resolute attack against the province on the other side. I lose no time to let you know this intention of the Arch-duke, being persuaded, after the disposition you have been pleased to exert, and which are used to direct your motions, that every exertion will be employed from your part to answer the above proposition. “I have the honour, &c. “L’EPINE, MAJOR GENERAL.” “COMMODORE BRENTON, COMMANDER OF H. B. M. FORCES, ADRIATIC.” This letter was accompanied by another, containing a list of the Austrian flotilla, with which Captain Brenton was desired to co-operate, consisting of two brigs of war, and a tartane stationed between Goro and Malamoco, with three gun boats, and five patrolling boats in the neighbourhood of Cortelazzo. The vessels were especially intended to prevent any supplies getting into Venice coastwise. It then added, “In Venice the enemy have at this time 7800 men: French, Italian, and militia. They have also In the Lagune 4 gun boats, and 3 floating batteries. At Malamoco 3 brigs, 3 gun boats, 3 floating batteries. ” Lido 2 brigs, 2 ” ” Treporte 1 gun boat, 1 gun pirogue. ” Venice 1 forty gun frigate, loaded with arms and ammunition, not intended to go out, and fifty-nine gun pirogues disposed in the remainder of the Lagune. The Arch-duke John had got as far as Verona, but will not probably advance further till the Arch-duke Charles shall again take the offensive. “Signed, “L’EPINE, MAJOR GENERAL.” “COMMODORE BRENTON, &c. &c.”
