Pursuit Trihemiolia, Mercenary Peltasts

Description

It is thought that the Rhodians, a significant naval power in the eastern Mediterranean, developed the 'trihemiolia' or 'two-and-a-half' as a vessel for pirate hunting. Given that Rhodes is an island entirely reliant on the sea and shipping this is a believable theory. Pirates used the hemiola, a handy little vessel developed from the dieres or bireme, a ship with two rows of oars; it makes sense that pirate hunters would think of taking a trieres, or trireme, with three rows of oars and modifying it in a similar fashion. A trihemiolia still had three rows of oars on each side, but the top row was reduced to only half the number of oars, positioned midships. The result was a faster, handier vessel that provided a height advantage over a hemiola for any archers on board. There was also a strategic benefit to the Rhodians, who could only draw on the manpower of one island: they could have six trieres warships with full complements of rowers, or seven trihemiolias for the same number of men. The useful design was soon adopted by other maritime powers around the Mediterranean.

These skirmishers were named for their small crescent-shaped leather or wicker shields or 'peltai'. It was a common habit to name troops for their shield style in the Greek world. They wore little or no armour and carried three javelins. After harassing the enemy by flinging javelins, they would hastily retreat before any counter-charge or flanking move could be carried out. As armies developed and tactics became more complex, peltasts were expected to take part in hand-to-hand combat: with such expectation they were given stiffened linen cuirasses and short swords. They were still expected to use javelins, but could then join in the close fighting. Eventually, peltasts even exchanged their characteristic shield for the heavier thureos. Their name and battlefield function remained unchanged.
