Both the Jackdaw and Swordfish raised their black flags at the same time, racing to the Spanish treasure ship as fast as their sails could carry them. Although the Jackdaw was closer to the Spanish ship, the Swordfish caught up to the Jackdaw in no time. The moment their ships were aligned, Brook slowed down and moved at the Jackdaw's speed. He did this knowing that the enemies will focus their fire on the Swordfish if Brook overtook the Jackdaw.
There was a 200-meter gap between the Jackdaw and the Swordfish. Being this close to each other, they could quickly help the other if necessary. At the same time, they hadn't gotten too close to the point where they would lose their agility as well.
The Spanish convoy finally saw their enemies. Immediately, they slowed down and maneuvered their ship so that their side cannons pointed at the enemies. They were at the ready to get into a battle with Zhang Heng and Brook.
