Back to each fortress dun:
Ponderous words speaks every monster gun.
Fearless they flash through gates of flame,
The salamanders hard to hit,
Though vivid shows each bulky frame;
And never the batteries intermit,
Nor the boats huge guns; they fire and flit.
Anon a lull. The beacon dies:
“Are they out of that strait accurst”
But other flames now dawning rise,
