Explanation: In the First Punic War, the Romans started the war without a navy or any naval experience. So they found a Carthaginian ("Punic") shipwreck, copied it 100 times, and voila! Instant navy!

... they lost that fleet.

So they built another!

... they lost that fleet too.

So they built ANOTHER!

They may also have lost that, or a related fleet.

Somehow, inexplicably, they managed to win the First Punic War anyway.

Stubbornness is a hell of an advantage.
