Although Rome had conquered nearly the entire old world, the use of the
ships in war was discovered quite late, but when it was necessary, the
Romans were able to prepare a fleet in a short time.
They were aware that the experience of their enemies was much more advanced,
so they decided to fight against them on the field, where they had more
experience in hand to hand combat.
Romans equipped their ships with particular bridges similar to drawbridges
of medieval castles.
On the end of the bridge was a spur, which landed on the other ships flank.
At this point, it became a land battle.
The bridges were called "corvi" (crows) and the ships "galere".
