On November 15, 1889, the prince was in the East, on board "Almirante Barroso" - who was on his first circumnavigation trip - when a coup d'état ended the monarchist regime in Brazil. Communication difficulties prevented the crew from learning about what happened before December. Telegrams of Admiral Wandenkolk - now Minister of the Navy of the provisional government - instructed the commander of the cruiser to replace the imperial insignia of the flags and to induce Augusto to resign. After consulting his grandfather and his uncle, the Count d'Eu, the prince decides not to resign, but to request a license of two months. In telegram, the minister responds to the request: "Prince resignation service, I grant leave. Wandenkolk."
