The Arcadian, built initially as the RMS Ortona in 1899 and later converted into a troopship during World War I, was en route from Salonika to Alexandria, transporting soldiers and medical personnel, when it was attacked on 15 April, 1917 and sunk by the German U-boat SM UC-74, resulting in the tragic loss of 279 lives.

The Arcadian had just completed a boat drill when a single torpedo hit it between the bridge and the foremast and sank within six minutes. 1,058 people were rescued

Kostas Thoctarides told state news agency ANA his team had located the wreck of HMS Triumph at a depth of 670 feet at an undisclosed location in the Aegean Sea.

The HMS Triumph was a British T-Class submarine involved in military operations in the Aegean Sea and elsewhere in the European theatre of the Second World War. It carried out twenty missions, including attacks against Axis ships, landing British commandos and rescuing Allied soldiers, until it disappeared during a mission in 1942. Eighty-four submariners were killed when the HMS Triumph sank.

Greek portal ScubaHellas reported that the German plane was located and identified by the technical diver and explorer Nikolas Giannoulakis, who also happens to be the owner of Chania Diving Center.

Greece has lifted diving restrictions eliminating depth limits and allowing diving at archaeological sites and sunken ships without an escort. The move follows a passed 2019 bill easing scuba diving laws and is part of a larger group of incentives to encourage the return of international tourists following the worldwide coronavirus pandemic.

Greek archaeologists have discovered the remains of a massive Roman vessel believed to be the largest classical shipwreck found in the eastern Mediterranean. Believed to have sunk some 2,000 years ago, the 35-metre vessel was discovered at a depth of around 60m during a survey off Kefalonia, one of the Ionian islands off Greece’s west coast. The site is situated 1.5 miles from the entrance to the harbour of Fiscardo, the island's only village to not be destroyed during World War II.

HMHS Britannic was the largest ship to sink during World War I. (Weighting in at almost 50,000-tons she was also the largest ship in the world).

Many argue she is one of the most beautiful, intact, well-preserved passenger liners accessible to divers. It is little wonder that these factors, and the story behind her construction and sinking continue to capture divers imagination.
