Description
The 'one-and-a-half' or 'hemiolia' was a light galley which was much favoured by pirates in the ancient world. It developed from the bireme, a ship that had two full decks of oars along its entire length. The hemiola reduced the number of oars on the upper level, leaving roughly half the number of oars and rowers in the midship section. The smaller number of rowers had little effect on overall speed because the laden weight of the vessel also dropped. Because it used both oars and sails, and the crew could rapidly change propulsion method, it was an ideal vessel for chasing down fat, wealthy merchant ships. Boarding attacks were mounted from hemiolas; ramming was not a useful tactic as loot ended up with the fish rather than enriching the pirates! The speed and handiness of hemiolas made them useful as scouts, supply boats and vessels used to pick off damaged enemies at the edge of battles.
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.
