Mission to the third moon of Concord Dawn

During the early rebellion against the Galactic Empire, the rebels Kanan Jarrus and Sabine Wren went on a mission to the third moon of Concord Dawn. Jarrus intended to secure an alliance with Fenn Rau, leader of the Protectors of Concord Dawn, so the rebels could safely pass through the Concord Dawn system—or, if diplomacy failed, destroy the Mandalorians' Fang fighters so they could not attack the rebel fleet when it moved through the system. Wren, meanwhile, invoked the Mandalorian code to challenge Rau to single combat as justice for the injuries he inflicted on Captain Hera Syndulla during a dogfight over Concord Dawn. The mission was a success; the rebels captured Rau, leading him to agree to let the rebels pass through his system.
