Historically, the Octopi consider the Battle of Gibb to be the first battle of Gibb, despite the fact that it is the second time the human raiders attacked. The original raid is called the Raid of Gibb and they do not consider it a battle, considering how one sided it was.
Edit: I’m happy to let others play with my octopus people. But to let them know how their first war is going to go: They win the battle of Gibb and launch a counterattack. However, things escalate due to another warlord taking over the southern island during the battle of Gibb… thus when the Octopi show up and attack, they’re fighting someone who has never encountered them before. The octopi for their part don’t notice the minor differences.
