A centennial commemoration event for World War I was held Sunday at Aloha Tower.
Military members, veterans and civilians gathered for the event.
The ceremony at the Aloha Tower Marketplace commemorated the sinking of the merchant ship, the S.S. Aztec, which was a factor in America's decision to declare war on Germany and their allies.
Six merchant mariners from Hawaii died in the attack by a German U-boat in the Atlantic.
"I think it's important that we all remember the sacrifices paid in blood by veterans of previous generations. Veterans, civilians too, the efforts that have led to the rights, the privileges that we have," Curtis Manchester of the WWI Centennial Task Force said.
Gov. David Ige signed a proclamation declaring April 2 as World War I Centennial Remembrance Day.
After the dockside tribute, people headed out to scatter flowers in the ocean to honor those killed in the attack.
