Quinquereme
From Wikipedia, the free encyclopedia
A quinquireme is a warship propelled by oars, developed from the earlier trireme. It was used by the Greeks of the Hellenistic period and later by the Carthaginians and Romans, from the 4th century BC to the 1st century.

[edit] Construction
In the 4th century BC, after the Peloponnesian War, there was a shortage of oarsmen of sufficient skill to man large navies of triremes. The search for designs of galley that would allow oarsmen to use muscle power instead of skill led Dionysius of Syracuse to build tetreres (quadriremes) and penteres (quinquiremes). For a long time, modern scholars were confused by the word penteres. If they were analogous to trieres (triremes) they would have had five rows of oars, but such a galley would surely have been impossible to construct and impossibly unstable. Later accounts talk about hexeres, hepteres and even larger galleys than those; clearly a different classification scheme was in operation.
There are no explicit descriptions or archeological remains of quinquiremes, so the construction is unclear. According to modern historians, the numbers used to describe galleys counted the number of rows of men on each side, and not the numbers of oars. There were thus three possible designs of quadrireme: one row of oars with four men on each oar, two rows of oars with two men on each oar or three rows of oars with two men pulling the top oars on each side (probably galleys of all three designs were built). Quinquiremes are thought to have had three rows of oars, with two men pulling each of the top two oars.
It had become apparent at the Battle of Syracuse in 413 BC that the topmost tier of rowers, the thranites, were vulnerable to attack by arrows and catapults, so the newer vessels completely enclosed all the rowers below the deck. According to Polybius, a quinquireme had a complement of 300 oarsmen, 120 marines, and 50 crew. Historian Fik Meijer suggests that on each side of a quinquireme there would have been 58 thranites pulling 29 oars, 58 zygites (the middle row of oarsmen) pulling 29 oars and 34 thalamites (the bottom row) with an oar each.
Quinquiremes were even more difficult to make stable than triremes, and the increase in speed was not so great as to give the larger galleys much of an advantage. Therefore smaller navies had a core of trireme warships, while bigger navies like Egypt, Rome and Carthage were able to afford a large number of quinquiremes and polyremes. Their advantage was the protection against ramming attacks and the larger body of marines. Comparing the effect of multiple man oars to one man oars you have to look at several men as not fully participating. Because of the restricted movement a large number of rowers did not propel the vessel with as much of their musclepower as on a one man oar. At this time the Greek homeland had declined as a naval power. Only Macedonia's uniting rule was able to afford these juggernauts in larger numbers and with its decline the fleet had to use cheaper triremes again to keep at least a large number of ships in the battleline. But this type of ship had changed into a heavier warship with the rowers now all protected under deck, much more firepower and marines.
Certainly quinquiremes were not produced in large numbers, except for a few dominant navies and triremes remained the mainstay of the Mediterranean navies. According to Polybius at the beginning of the First Punic War, Rome had 10 triremes for coastal defence. After this war, the Romans had the supreme navy of the Mediterranean. During the Second Punic War Rome had 220 and before the first punic war Carthage at least 300 quinquiremes. A medium sized seapower like the kingdom of Pergamon had 100 triremes.
[edit] Polyremes
The wars of the Diadochi, the successors to the empire of Alexander the Great, caused another arms race. This time the trend was to build bigger and bigger galleys. Macedon was building hexiremes (probably with two men on each of three oars) in 340 BC; by 315 BC Antigonus, the successor to Alexander the Great in Macedon, was building septiremes, which saw action at the Battle of Salamis in Cyprus (306 BC); his son Demetrius, involved in a naval war with Ptolemy of Egypt, built eights (octeres), nines, tens, twelves and finally sixteens.
A change in the technology of conflict had taken place to allow these juggernauts of the seas to be created, as the development of catapults had neutralised the power of the ram, and speed and manoeuvrability were no longer as important as they had been. It was easy to mount catapults on galleys; Alexander the Great had used them to considerable effect when he besieged Tyre from the sea in 332 BC. The catapults did not aim to sink the enemy galleys, but rather to injure or kill the rowers (remember that a significant number of rowers out of place on either side would ruin the performance of the entire ship and prevent its ram from being effective). Now combat at sea returned to the boarding and fighting that it had been before the development of the ram, and larger galleys could carry more soldiers.
Some of the later galleys were monstrous in size, with oars as long as 17 metres pulled by as many as eight rowers. With so many rowers, if one of them was killed by a catapult shot, the rest could continue and not interrupt the stroke. The innermost oarsman on such a galley had to step forward and back a few paces with each stroke.
The very largest galleys were probably catamarans, according to J. S. Morrison. An account by Memnon describes how Demetrius' rival Lysimachus of Asia Minor built a galley, the Leontophorus, so large it required 1600 rowers and could support 1200 marines. Plutarch described a quadragintareme (forty) built for Ptolemy IV of Egypt in about 200 BC that was 128 m long, required 4,000 rowers and 400 other crew, and could support a force of 3,000 marines on its decks. He wrote, "This ship was only for show. It scarcely differed from buildings which are rooted in the ground and had great difficulty in being put to sea."
[edit] Roman
The large galleys must have been very sluggish and could be defeated by large numbers of smaller ships. The Roman navies consisted of triremes, quadriremes and quinquiremes. Though armed with a ram, these ships usually fought by boarding rather than ramming. The Romans during the First Punic war used a special ramp with a spike that would be droped onto an enemy ship to facilitate boarding. This device was called a corvus or "crow". But this invention led to the destruction of complete fleets during storms. Therefore at the decisive battle of the Aegates Islands and afterwards it was no longer employed by the Roman Navy. According to Polybius another invention was called the "bear" and simply hit the enemy ship like a ram, but did not penetrate the hull. It was used to unbalance it and throw parts of the crew out of their rowing benches or from deck.
In the last great naval battle of the ancient world, at Actium in 31 BC, Octavian's lighter and more manoeuvrable ships defeated Antony's heavy fleet. These lighter ships increasingly relied on shooting and burning the enemy. After that, with the Roman Empire in charge of the entire Mediterranean, a heavy navy was no longer needed. By 325 there were no more quinquiremes. Still there were naval wars to fight piracy from time to time and the fleet was politically influential because it controlled the grain supply.
