The first objective of the invading army was an outlying village of the enemy. This might be a fortress on a hilltop, strongly entrenched by nature, or a village in the plain, defended with an earthwork about six feet high, surmounted with a breastwork of reed fencing or cocoanut trunks, and surrounded by a muddy moat. Sometimes there was a double or a triple moat with earthworks between. There is endless variety in these fortifications, for advantage was always taken of the natural defences, and almost every important hilltop in Western Vitilevu is crowned with an entrenchment of some kind. Though there were generally from four to eight gateways, defended by traverses, and surmounted with a look-out place, some strongholds had but one gateway and that so difficult of access as to be impracticable to the besiegers. The fort of Waitora, situated on a hill two miles north of Levuka, is a rock about twenty feet higher than the surrounding ground, and inaccessible save by means of a natural ladder formed of the aerial roots of a huge banyan-tree, which arch over at the top so as to form a tunnel just big enough to admit the body. The great rock fortress of Na-koro-vatu on the Singatoka river was taken in the rebellion of 1876 by surprising the only approach on a Sunday morning, when the rebels thought that the government troops would be in church. The besiegers crept up a jagged rift in the rock as steep as the side of a well, and utterly impregnable against more vigilant defenders. In the island of Vatulele, an upheaved coral reef honeycombed with caverns, the fortress of Korolamalama was a cave defended by a breastwork of stones, watered from a well in its inmost recesses, and provisioned for a siege of many months. The last stronghold of the rebel mountaineers in 1876 was a cave large enough to contain the population of all the neighbouring villages, and impregnable to every weapon except smoke, an expedient commonly employed by the force attacking such defences. On the other hand, the chief towns of large confederations, such as Mbau, Mathuata and Rewa, were not fortified at all, because if the enemy had been victorious enough to approach them, their inhabitants would have seen that all was lost and would have sued for peace.
