The battle fleets, the vast Ptolemaic battle fleet purchased by Cleopatra's money is at Harbor, hundreds of ships at

harbor with merchant ships back and forth feeding the army, whereas the

smaller Roman fleet is is north of Actium on the coastline without easy access, but Octavian

and Agrippa have fought sea battles before.

Professor, what is a five, what is a six? What kind of ships are those?

So these are galleys.

They are oared ships.

And a five would, there's some doubt as to how they were made up, but I think according to the most likely reconstruction.

In a five, you'd have five men to a room. Imagine two ores, there are three men rolling on the top level and two men

Six might have three and three.

A four and a five are about the most efficient kinds of warships to use in this period.
