How the HMAS Sydney was destroyed by a German merchant ship half its size

The sinking of the HMAS Sydney was the biggest and bloodiest war mystery in Australia, giving rise to a series of strange conspiracy theories (a digital reconstruction of the battle is shown in the image)

The sinking of the HMAS Sydney was the biggest and bloodiest war mystery in Australia, giving rise to a series of strange conspiracy theories.

The shipwreck hunter David Mearns found the ship sunk in 2008, and now the new technology has allowed the experts to reconstruct the last moments of the ship.

Using sophisticated computer graphics, the new National Geographic series, Drain the Oceans, provides stunning images of the HMAS Sydney while at the bottom of the sea.

The incredible images, created with a special technique of "drainage", show the final position of the Sydney HMAS towers and the smallpox marks of the German weapons.

Thanks to the innovative technique, the battleship can now be seen in detail for the first time in almost 80 years, and new light has been thrown on its last battle.

HMAS Sydney went down in the Indian Ocean off the coast of Western Australia after an intense battle with the German merchant ship Kormoran on November 19, 1941.

All 645 sailors aboard the Australian ship were lost, and 317 Nazi crews were captured after the Kormoran was sunk.

Electric Pictures CEO Andrew Ogilvie said that a special "drainage" technique allowed filmmakers to show viewers what the shipwrecks would be if the water were removed.

For years, the savage conspiracy theories about Japanese cover-up and participation prospered, until Mr. Mearns' expedition finally put the mystery to rest.

After associating with the Australian government, Mearns used the clues left by Kormoran's captain, Theodor Detmers, to determine the location of the ship.

The discovery of the German auxiliary cruiser was followed by HMAS Sydney five days later, which sank with Captain Joseph Burnett in the lead.

A thorough examination of the wreck showed extensive damage caused by German missiles and torpedoes, and explained why the ship sank without survivors.

The Kormoran was equipped with pistols hidden behind fake hull plates and secret torpedo tubes, allowing him to cheat the largest Australian ship.

When the crew of the HMAS Sydney realized that they had found an enemy ship, it was too late and the Kormoran was able to overcome its armor and range disadvantages and sink the Australian ship.

The battle marked the largest loss of life in Australian naval history, accounting for 35 percent of the deaths of Australian Royal Navy personnel during World War II.

Drain the Oceans is a co-production between the Australian producer Electric Pictures and Mallinson Sadler Productions, based in the United Kingdom, and premiered on August 7.

Electric Pictures CEO Andrew Ogilvie said the special technique of "drainage" allowed filmmakers to show viewers what the shipwrecks would be if the water were removed.

"Bathymetric probes, video sequences and photogrammetry with sophisticated computer-generated graphics were used to create high-precision three-dimensional models of the bottoms of our oceans, lakes and rivers," he said.

"This process allows filmmakers to recreate natural wonders, wrecks, ancient ruins and other human artifacts that can be found in the depths of the sea, revealing them in unprecedented detail, as if they were on solid ground.

"For the first time, we can see what these places look like on a large scale and with a clarity that is simply not possible using traditional underwater photography."
