Originally a steam-powered fishing vessel named Elite. The vessel was requisitioned by the Portuguese government to serve as a patrol boat during World War I.[2]
On 23 March 1918 Augusto de Castilho, commanded by Lieutenant Augustus de Almeida Teixeira, was convoying the transport ship Loanda when a submarine was spotted. The Portuguese patrol ship opened fire at about 500 metres (1,600 ft) at the unidentified submarine, which dived promptly.[3] On 21 August 1918, commanded by Lieutenant Fernando de Oliveira Pinto, Augusto de Castilho attacked a large German submarine with gunfire that disappeared quickly.
On 13 October while escorting the passenger ship São Miguel, Augusto de Castilho, under the command of First Lieutenant Carvalho Araújo, sighted by the German submarine SM U-139. The submarine, commanded by Lothar von Arnauld de la Perière, tried to attack the passenger ship but failed due to the intervention of Augusto de Castilho. The Portuguese patrol ship was armed with two Hotchkiss gun pieces, a 65 mm caliber gun at the bow and a 47 mm caliber gun at stern, while U-139 was armed with two 150 mm naval guns and six torpedo tubes. The Portuguese warship was sunk after a fierce two-hour battle with the loss of four crewmembers, among them Carvalho Araújo.[4][5]
