An exploding enemy artillery shell killed and wounded 13 Canadians aboard HMCS Iroquois, tearing open this cartridge casing in the process.

The mangled brass demonstrates the danger posed by enemy coastal artillery. On 2 October 1952, a shore-based gun hit Iroquois while the destroyer was bombarding the railway along Korea's east coast, instantly killing two and wounding 11 others, one of whom died shortly afterwards. Fragments from the blast ignited this cartridge and its attached shell, which exploded. Iroquois moved out of range to assess the damage, make repairs, and treat the wounded before resuming its patrol.
