They still had good cover, as fallen timber was scattered all over the oasis, and they were quite sure that another attack would be made soon.

It came in about fifteen minutes.

The Iroquois suddenly fired a volley at the logs and brush, and when the five returned the fire, but with more deadly effect, they leaped forward in the mud and attempted to rush the oasis, tomahawk in hand.
But the five reloaded so quickly that they were able to send in a second volley before the foremost of the Iroquois could touch foot on solid earth.

Then the double barreled pistols came into play.

The bullets sent from short range drove back the savages, who were amazed at such a deadly and continued fire.
