line-of-battle ship

On April 28 a heavy line-of-battle ship was sighted, and gave chase.

Soon after this Sir Sidney passed within hail of a line-of-battle ship at anchor.

The stranger appeared high out of the water, and we could not be certain whether she might not be a line-of-battle ship.

At this crisis, for an instant, as the smoke cleared off, another line-of-battle ship was seen approaching the Brunswick.

The Constitution was probably the heaviest frigate afloat, and able to withstand a cannonade as well as any line-of-battle ship.
