Caissons [noun]

The largest dock is divisible by a central caisson so that four ships can be docked at one time.

The first shot did no execution, but the next struck a caisson and exploded its contents.

Commanders of batteries will see that their limber and caisson-boxes are filled to their utmost capacity.

The reserve men cut the gear of the dead horse, dragged his body aside, and replaced him with one of the six from the caisson.

The horses became entangled among the ropes, and stumbled over the gun and caisson, throwing their riders to the earth.

The ground over which they had fought was a soaking red mire, and the wheels of cannon, caisson, and limber were sunk deep in it.

The chief of caisson was promoted to the command of the gun, and took his new office without friction or delay.

All the men moved up another step, but both the gun and the caisson were shorthanded.

The chief of caisson proceeded to supply ammunition to the gun, which did not slacken its industry.

At an almost equal distance in the rear of the limber stood the caisson, also with its six horses.
