The Battle of Bladensburg, which took place on August 24, 1814, during the War of 1812, was a significant conflict that resulted in a humiliating defeat for the United States. A British force, including army regulars and Royal Marines, routed a combined American force of Regular Army and state militia troops.

The battle itself was marked by tactical errors on the American side, disorganization, and a lack of preparation. The British forces, led by Ross, advanced swiftly and defeated the American defenders, resulting in a retreat and the subsequent burning of Washington, D.C. Despite heavier casualties, the British achieved a decisive victory, while the American forces faced criticism and labeled the battle as a disgrace in their history. This defeat had a lasting impact on the course of the War of 1812 and American perceptions of their military capabilities during that time.
