h e limited number of ships that medieval kingdoms and peoples were
capable of amassing was particularly evident in the years directly following
the Roman Empire’s demise. Moreover, the vessels of that period
lacked the speed, storage capacity, and overall military ef ectiveness of
those in the later Middle Ages. h e earlier ones were galleys much like
those employed by the Greeks, Romans, Phoenicians, and other ancient
Mediterranean peoples. h ey operated primarily by
the power of men pulling long oars. h e single, small,
square-shaped sail that such a ship carried could sometimes
supplement the rowers. But it was incapable of
powering the vessel for very long in most situations.
A typical early medieval galley was about 100 feet
(30 m) long and featured twenty-i ve oars on each side.
In naval terminology, those oars are more often called
“benches” in reference to the wooden seats on which
the rowers sat. With one man to a bench, there were therefore i fty rowers.
Some of the early galleys had two banks of benches, one situated
above the other, in which case there were one hundred rowers. Such a
vessel also had a few sailors to maintain and guide it and a small number
of marines (naval i ghters). h e rowers were expected to i ght alongside
the marines during a clash with an enemy.
Because these ships were relatively small yet carried quite a few people,
there was no room for large stores of food and other supplies. h is meant
that they could not remain at sea for more than a few days at a time. For
this reason, as well as the lack of ef ective navigation instruments, galleys
usually stayed within sight of coastlines and made frequent stops.
Closely related in many ways to the early Mediterranean galleys, although
smaller, were the oared boats that plied the waters of the North
Sea. Chief among these were Viking longships. One that was unearthed
in modern times—called the Gokstad ship—appears to be typical of the
average longship in most ways. It is 76 feet (23 m) long and has sixteen
benches to a side, which means it had thirty-two oarsmen. Partly because
the Normans were descendents of Vikings who had settled in France, the
oared vessels that Duke William built to carry his army across the English
Channel in 1066 were very similar to longships.
