Jolly Roger - Use in Practice

Use in Practice

Pirates did not fly the Jolly Roger at all times. Like other vessels, pirate ships usually stocked a variety of different flags, and would normally fly false colors or no colors until they had their prey within firing range. When the pirates' intended victim was within range, the Jolly Roger would be raised, often simultaneously with a warning shot.

The flag was probably intended as communication of the pirates' identity, which may have given target ships an opportunity to change their mind and surrender without a fight. For example in June 1720 when Bartholomew Roberts sailed into the harbour at Trepassey, Newfoundland with black flags flying, the crews of all 22 vessels in the harbour abandoned them in panic. If a ship then decided to resist, the Jolly Roger was taken down and a red flag was flown, indicating that the pirates intended to take the ship by force and without mercy. Richard Hawkins reports that "When they fight under Jolly Roger, they give quarter, which they do not when they fight under the red or bloody flag."

In this view of models, it was important for a prey ship to know that its assailant was a pirate, and not a privateer or government vessel, as the latter two generally had to abide by a rule that if a crew resisted, but then surrendered, it could not be executed:

An angry pirate therefore posed a greater danger to merchant ships than an angry Spanish coast guard or privateer vessel. Because of this, although, like pirate ships, Spanish coast guard vessels and privateers were almost always stronger than the merchant ships they attacked, merchant ships may have been more willing to attempt resisting these "legitimate" attackers than their piratical counterparts. To achieve their goal of taking prizes without a costly fight, it was therefore important for pirates to distinguish themselves from these other ships also taking prizes on the seas.

Flying a Jolly Roger was a reliable way of proving oneself a pirate. Just possessing or using a Jolly Roger was considered proof that one was a criminal pirate rather than something more legitimate; only a pirate would dare fly the Jolly Roger, as he was already under threat of execution.
