War I. He also oversaw the increasing militarization of the Hawaiian Islands. The entire coastline of the island of Oahu was fortified and several United States military bases were established, including: Fort Shafter, Pearl Harbor and Schofield Barracks. With the absence of an established military ordinariate in the United States, Msgr. Boeynaems ministered to Catholic service members. After a period of illness, Msgr. Boeynaems died on May 13, 1926, and was buried in Honolulu Catholic Cemetery. Alencastre When Msgr. Boeynaems became ill, Pope Pius XI elevated the first person to have grown up in the Hawaiian Islands to become a vicar apostolic. The pope appointed Stephen Peter Alencastre, a Picpus Father born in Portugal who was brought as an infant to the Hawaiian Islands with his family to live. Msgr. Alencastre was raised and educated in Hawaii, living on the various islands. He subsequently graduated from Saint Louis College and was accepted into the Congregation of the Sacred Hearts. He was ordained to the priesthood and educated in Europe by the Picpus Fathers, earning a doctorate in sacred theology.

Rather, its flourishing Catholic community was mature enough to be administered as a fully independent body of its own. The pope canonically erected the new Diocese of Honolulu on January 25, 1941.
