She was an escort carrier - one of the converted American merchant ships that the British called the Avenger class - and the wartime government had urgent reasons to keep what happened to her quiet. The local press was instructed to make no reference to the tragedy. Families were told their men had died on service but not where, not how, not in any way they could grieve cleanly. The cover-up was successful enough that the cause of the explosion was not officially confirmed for nearly seven decades. The men who died are still on the bottom of the Clyde, in waters their loved ones could see from the shore.

The government of the time, eager to avoid damage to morale and anxious to avoid any suggestion that the American-built carriers were structurally unsound, tried to cover up the sinking. The local media were ordered to make no reference to the tragedy. There were persistent rumou...

Pieces of Dasher's wooden flight deck washed up on the Firth's beaches in the days and weeks after the sinking, riddled with the small tunnels of burrowing teredo worms - shipworms that had bored through the wood while it lay on the bottom or floated half-submerged.
