[Robert A Cook PE]

One classic (though can't be positive it is the one you're referencing) is of an ammo ship exploding off of Anzio in the Med.

Tragedy there: It had gas shells on board, but nobody (surviving) knew it: They leaked and spread phosgene (probably) across the water, and the survivors of the explosion got nasty chemical burns from the floating residue.

If I can find the VHS tape I have it on, I will upload it to zippy or youtube, I would like to learn the circumstances behind this explosion.
