On the 6th of October, the squadron left Supa for Macassar, carrying away the troops, with the exception of one hundred men, who were left under the command of Captain Van Doornum. The brig under my command, together with a gun-boat, also remained, and we were soon joined by the corvette Courier. On the 20th, I sailed for Macassar, and two days afterwards, when off Tannette, a number of prahus were seen standing in towards the fort there, in which we had a garrison of fifty men. On perceiving the brig the prahus altered their course and stood out to sea, a proceeding which aroused my suspicion, and as the sea breeze prevented me from following them, I ran in, and brought up off the mouth of the river. A small prahu soon came alongside, bringing the information that the fort was beset on the land side by the enemy, who threatened an attack with so large a force that our small garrison could not possibly resist. The commandant wished to embark his men in the brig and desert the fort; but as I could not receive them without having received orders to that effect from the governor, I sent one of the small vessels that attended the brig to Macassar, to make known to the authorities there the hazardous position we were in. It appeared that the enemy intended to have attacked the fort both by sea and land, in which case not one of the garrison would have escaped. My accidental arrival had fortunately prevented this double attack, which would not have been the case had I come a day later, or had I missed the prahus, the appearance of which caused me to anchor off the fort. I therefore thanked Providence for leading me to adopt the route which brought me near the besieged place, the garrison of which, but for this opportune visit, must have experienced the same fate with that which had already befallen those of Labakang and Pankalina. On the following day the brig Nautilus arrived to relieve us. In the mean time the people of Boni had risen, all the tribes to the northward of Macassar being now in arms against us. The town of Macassar was often threatened by the enemy, but they never ventured an attack, being deterred by the force our ally, the king of Goa, had brought into the field, and by the reinforcements that arrived from Java. Preparations were now made for a grand expedition, the troops that had been left at Supa and Tannette being withdrawn from their uncomfortable posts to join the main force at Macassar.
