In the early hours of April 27, 1865, a steamboat packed with nearly two thousand exhausted Union soldiers drifted northward on the Mississippi River. The American Civil War had ended and these soldiers who had survived battlefields, diseases, and some of the Confederacy’s most notorious prison camps were finally going home.

Shortly after 2 a.m., the vessel's boilers exploded with tremendous force throwing men into the river and trapping hundreds beneath collapsing decks. Flames engulfed the wooden steamboat. By the time the disaster was over, more than a thousand people had perished, making the Sultana tragedy the deadliest maritime disaster in American history. Yet unlike the sinking of the Titanic, it remains largely unknown today.

In the frigid waters of the Canadian Arctic, nearly 100 meters beneath the surface, lies a ship seemingly untouched by time. Despite the passage of more than a century, she is more or less intact, except for a gaping hole in her starboard side. Two of her masts still rise from the seabed.

The ship is Breadalbane, the world’s northernmost known shipwreck, and also one of the best-preserved wooden ships ever found in the sea. She lies approximately 1,000 km south of the North Pole.
