Maritime trade warfare, also called commerce warfare, is a naval/military strategy that has been followed since ancient times. 1 The idea of maritime trade warfare is to attack or neutralize the commercial shipping of one’s enemy in an effort to disrupt the enemy’s economy, make it more difficult for the enemy to continue waging war by disrupting the enemy’s military supply chain that uses the sea, or both.
