Loot

Even though pirates raided many ships, few, if any, buried their treasure. Often, the "treasure" that was stolen was food, water, alcohol, weapons, or clothing. Other things they stole were household items like bits of soap and gear like rope and anchors, or sometimes they would keep the ship they captured (either to sell off or keep because it was better than their ship). Such items were likely to be needed immediately, rather than saved for future trade. For this reason, there was no need for the pirates to bury these goods. Pirates tended to kill few people aboard the ships they captured; usually they would kill no one if the ship surrendered, because if it became known that pirates took no prisoners, their victims would fight to the last breath and make victory both very difficult and costly in lives. In contrast, ships would quickly surrender if they knew they would be spared. In one well-documented case 300 heavily armed soldiers on a ship attacked by Thomas Tew surrendered after a brief battle with none of Tew's 40-man crew being injured.
