[edit] Sinking of the Kalingo

In January 1943, off the East coast of Australia, the I-21 sank the ship Kalingo, with loss of two of the Kalingo's crew.

[edit] Sinking of SS Iron Knight

The BHP iron ore carrier SS Iron Knight was part of a convoy of ships travelling up the East coast of New South Wales on February 8, 1943. Under cover of darkness at approximately 2:30 am, the I-21 fired a torpedo at the naval ships flanking the Iron Knight at the head of the flotilla, however the torpedo passed under the bow of the Bathurst class corvette HMAS Townsville and struck the Iron Knight, sinking her with the loss of 36 crew in less than two minutes. Most of the ship's crew were below decks and were unable to escape the ship as she went down. Only 14 of the crew survived, clambering on board a single lifeboat until they were picked up by the French destroyer Le Triomphant. The HMAS Mildura, the other corvette guarding the convoy, pursued the I-21 for several days.

On 4 June 2006, the wreck of the Iron Knight was discovered in waters off the New South Wales town of Bermagui at a depth of approximately 125 metres. Local fishermen had snagged their nets on the wreck over the years, unaware of the ship lying deep in the waters. Families and descendants of the crew, travelled out to the site, and laid a wreath and poppies on the waters surface above the wreck. The sole remaining survivor of the sinking, John Stone, was unable to make the journey from his home in Southern Victoria.
