When he had done so, he raised both his hands to a level with his shoulders, which was the signal to go ahead, and the men pulled a very slow stroke.

He continued to sound, after he had selected the point for landing.
When the first cutter was within three lengths of the shore, he elevated both his hands above his head, which was the signal to cease rowing, though the two bow oarsmen kept their oars in the water instead of boating them as the others did.

Mr.Amblen continued to feel the way, and in a few minutes more, aided by the shoving of the two bow oarsmen, he brought the boat to the shore.
Then he gave his attention to the second cutter, bringing it to the land alongside of the first.

Stepping out on the sand himself, he was followed by all the crew, with cutlass in hand, and revolvers in readiness for use.

The men were placed in order for an advance, and then required to lie down on the sand, so that they could not readily be seen if any stroller appeared on the ground.
Leaving the force in charge of Mr.Flint, Christy and Amblen walked towards the battery, crouching behind such objects as they could find that would conceal them in whole or in part.
