The Ambrose Light was a brigantine vessel involved in the Colombian Civil War of 1885, operated by Colombian rebels under a letter of marque from rebel leader Pedro Lara, which authorized the blockade of Cartagena. The ship was armed with a single cannon and carried a crew of approximately sixty heavily armed sailors, reflecting its role in wartime operations. Its physical characteristics, such as size and construction details, are not specified in the provided source. During an engagement on April 24, 1885, the Ambrose Light was sighted by the USS Alliance while en route to Cartagena. The American vessel, mistaking the ambiguous flag featuring a red cross on a white background for piracy, initiated a chase. Once stopped, a boarding party led by Lieutenant M. Fisher discovered that the vessel was armed and manned by rebels. The Americans seized the brigantine, considering it a pirate ship under international law, and took her as a prize. The captured vessel was taken to New York, arriving on June 1, where a stowaway was found starving in the cargo hold and was subsequently cared for. The legal proceedings that followed determined that the Americans had lawfully seized the Ambrose Light since the rebel leader Pedro Lara lacked the authority to commission ships as pirates under U.S. law. The court ultimately condemned the vessel but ruled that it could be legally used for transporting troops between Colombian ports during the civil conflict. Following the legal resolution, the United States returned the Ambrose Light to her Colombian owners in exchange for costs. When hostilities resumed in Cartagena, the U.S. Secretary of State Thomas F. Bayard ordered her release, reflecting her status as a legitimate vessel under Colombian authority. The incident involving the Ambrose Light became a notable case in maritime law, shaping the legal definitions of piracy and the legitimacy of rebel-commissioned vessels under U.S. jurisdiction.
