The cache didn’t end the war. The Spanish did. We had lost and retreated and had it not been for Billy spreading the Silver gospel the war would be over and Woodes would have had the Maroon camp hazed to the ground. The Brits were on the soil so they roughly know where it can be accessed. Likely difficult to get there though. And the Maroons would have lasted for a while but who’s to say.
I just wanted that clarified because I myself have thought of this cache as being defined in the scope of the war but honestly the pirates lost. They were ran off. By some miracle men came but these men are barely aligned and obviously greedy bastards looking to loot and rage in the face of the law.
That cache serves no purpose but to Flint and his way to have people follow him because as Dooley pointed out no one is doing it for the reason Flint is and thats something Flint knows and is more telling than anything about his motives.
