This sacred Hawaiian site once consumed three Europeans who ignored local warnings

HMS Daedalus Sailors’ Ritual Sacrifice at Pu’u O Mahuka

In May 1792, HMS Daedalus dropped anchor at Waimea Bay in Hawaii.

Three men went ashore against local advice – Lieutenant Hergest, astronomer Gooch, and a sailor named Manuel. Bad blood ran deep.

Just months before, a British man had got a ship to fire on Hawaiian chiefs. Now, the locals struck back.

Black-tattooed Pahupu warriors killed one sailor right away. They took Hergest and Gooch up the hills, where both men died that night.

Their bodies were likely carried to Pu’u O Mahuka Heiau for ritual sacrifice.

Today, this sacred temple still stands as Hawaii’s largest heiau, where visitors can walk the same ground where cultures clashed in blood.

British Betrayal Set the Stage for Hawaiian Revenge

In 1792, Englishman Isaac Ridley broke Hawaiian trust in the worst way.

After working for Oahu chiefs, Ridley left his job and talked the captain of British ship Grace into firing cannons at Hawaiian leaders. This shocking act turned friendly trading sour overnight.

Hawaiian fighters now saw all British sailors as threats, not partners.

Chiefs across the islands spread news of this betrayal, putting every coastal village on alert for the next British ship to arrive.

Supply Ship Daedalus Sailed Into Danger

HMS Daedalus left England in 1790 carrying supplies for Captain George Vancouver’s Pacific mapping trip. Lieutenant Richard Hergest took charge of the merchant ship even though he didn’t want to lead a non-Navy vessel.

Young star-watcher William Gooch joined the crew, eager to meet Vancouver. Portuguese sailor Manuel came aboard too.

The ship carried food, tools, science gear, and water collectors needed for Vancouver’s work mapping the Pacific Northwest coast.

Waimea Bay’s Calm Waters Hid Deadly Intentions

The Daedalus stopped at Waimea Bay on May 7, 1792, where Captain Cook’s ships had visited thirteen years before.

Lieutenant Hergest first kept the ship away from shore, calling the local Hawaiians "the most savage and tricky" among the islands.

Hawaiian crew members warned the British officers not to go ashore, feeling danger from their people. For several days, the ship stayed far out while crew carefully traded with locals in canoes.

Three Men Made a Fatal Trip to Shore

On May 11, Lieutenant Hergest changed his mind about staying offshore.

Against earlier warnings, he ordered the ship moved closer to land and went ashore himself with water barrels.

Hergest and Gooch walked onto Hawaiian sand with no weapons, joined by Portuguese sailor Manuel and a small boat crew.

The group split up, some stayed with the boats while others walked inland with empty water containers.

Black-Tattooed Warriors Launched a Swift Attack

Pahupu warriors attacked without warning that afternoon. These fighters, with bodies tattooed solid black on one side, surrounded the British landing party.

They killed one sailor right away on the beach, cutting off escape for Hergest, Gooch, and Manuel. The officers found themselves caught alive and forced up the steep hills behind Waimea village.

One "very strong active man" broke through the crowd and ran back to the boat to raise alarm.

Rescue Attempts Failed as Night Fell

Two survivors grabbed guns from their boat and tried hard to save their officers. Through the crowd, they spotted Hergest and Gooch still alive but naked and being pushed up the hillside.

Hawaiian warriors on surrounding hills threw stones at the would-be rescuers, keeping them from getting close enough to help. As darkness came, the rescue party went back to the ship to plan better.

The crew spent a tense night offshore, getting weapons ready for morning.

Morning Brought News of Ritual Killings

The acting commander gathered all officers at dawn to plan a rescue with full firepower. A Kauai chief who traveled aboard the Daedalus went ashore as a go-between, hoping to free the caught men.

He came back with bad news: both Hergest and Gooch had been killed during the night. Hawaiian warriors told him the bodies "had been cut in pieces, and shared among seven different chiefs.

Hawaii’s Largest Temple Loomed Above the Bay

Pu’u o Mahuka Heiau stood 300 feet above Waimea Bay, watching over the waters like a stone guard. Built in the 1600s, this huge temple covered nearly two acres, making it the largest heiau on Oahu.

The temple served as a war site for Ku, the Hawaiian god of war. High priest Ka’opulupulu ran the sacred place during this time of island conflict.

The temple had three walled areas with wooden buildings and stone altars made for human sacrifice.

Sacred Rituals Claimed British Bodies

Dig expert J. Gilbert McAllister wrote in the 1930s that the British bodies were "probably" taken to Pu’u o Mahuka Heiau after their capture and killing.

The temple was the right place for human gifts to Ku, especially when seeking wins against outsiders. The cutting and sharing of body parts among seven chiefs followed exact Hawaiian sacrifice customs.

Priests would have run the ceremony by strict rules, placing the remains on the temple’s stone altars.

Captain Vancouver Demanded Justice

Captain George Vancouver arrived in Hawaii ten months later in March 1793, angry about the deaths of his men. He told Hawaiian chiefs to hand over the killers for punishment under British law.

Warriors on shore threw stones at British boats trying to land, forcing Vancouver’s men to shoot their guns during retreat. His peace talks failed as Hawaiians refused to give up those responsible.

Vancouver left the islands without the justice he wanted.

Sacred Site Still Stands as Witness to Cross-Cultural Violence

The Daedalus incident remains one of the best-documented cases of Europeans becoming victims of Hawaiian sacred practices.

The temple continued operating until 1819, when King Kamehameha II abolished the traditional kapu religious system.

Pu’u o Mahuka Heiau became a National Historic Landmark in 1962, preserving the stone walls where European explorers encountered ancient Hawaiian traditions in the most violent way.

Today, visitors can walk among the same stone enclosures where British sailors likely ended their journey.

The site offers a powerful reminder of how cultural misunderstandings and broken trust transformed peaceful exchanges into deadly confrontations in Hawaii’s colonial period.

Visiting Pu’u O Mahuka Heiau, Hawaii

Pu’u O Mahuka Heiau is at the end of Pu’u O Mahuka Road in Pupukea on Oahu’s North Shore.

This free site is open during daylight hours and has interpretive signs explaining the 1792 incident when three British sailors from HMS Daedalus were killed and sacrificed here.

You’ll find a visitor altar where people leave offerings like leis. The heiau sits 300 feet above Waimea Bay with views of the coastline.

Don’t climb the stone walls.
