Left is for "Comandante Carvalho Araujo"
This man was born on May 18, 1881 in Porto.
After completing his studies at the Academia Politécnica do Porto, he enlisted in the Portuguese Navy in 1899.
He served on several ships: the frigate Dom Afonso, the corvette Duque da Terceira, the cruisers Vasco da Gama, Adamastor and São Rafael, the gunboats Zambeze, Liberaal, Diu and Lúrio, the tugboat Bérrio and the transport ship Salvador Correia. He was also Governor of the Inhambane District in the Portuguese colony of Mozambique for a while.
Carvalho Araujo died on October 14, 1918 while with the Portuguese naval trawler NRP Augusto Castilho protected the cargo ship São Miguel against the attack of the German U-boat SM U-139, commanded by Lothar von Arnauld de la Perière, commander of the submarine. He was then 37 years old.

The plate on the right: "Centenario do Combato do NRP Augusto Castilho".
Originally the NRP Augusto Castilho was a steam powered fishing boat called Elite. The ship was requisitioned by the Portuguese government to serve as a patrol boat on the high seas during World War I.
It was armed with artillery fore and stern.
On October 13, while escorting the passenger ship São Miguel, Augusto Castilho, under the command of First Lieutenant Carvalho Araújo, was sighted by the German submarine SM U-139. The submarine, led by Lothar von Arnauld de la Perière, attempted to attack the passenger ship, but failed due to the intervention of the NRP Augusto Castilho.
After a two-hour battle, with casualties and damaged artillery, the ship surrendered. Carvalho Araujo was fatally wounded in the submarine's last shot.
