The Long Blue Line: Revenue cutter operations in the Mexican-American War

On May 13, 1846, President James Polk signed the declaration of war with Mexico. Revenue cutter captain John Webster formed an 11-cutter squadron to blockade and patrol along the coast of Mexico. Until the end of the war in 1848, the crews of the squadron convoyed merchant vessels, transported troops and supplies, blockaded enemy ports, delivered important dispatches to naval commanders and played a vital role in shallow water combat and amphibious operations.
