What is the most important thing in this era?
Of course, it's transportation!
Pirates rely on superior longships to strike at the inland, occupying territories and leaving the Black Iron Duke powerless.
Why was Gael able to fight bitterly for two years, only to narrowly lose in the end?
Because he could continuously supply materials from the rear of the Riptide Domain through water transport.
Why does the Holy War Army dare to plan a ten-year blockade of the River Valley?
It's also because they can obtain supplies via water transport.
To put it bluntly, in any large-scale war, as long as one side has the advantage of water transport, they have practically won half the battle.
And ships are even more important for commerce.
Roman exchanged many longships from the pirates, which were all old and on the verge of being scrapped and would only last for a year or two more.
This kind of behavior is commonly known as scavenging.
