sent a few men below with pikes to the lower port-holes, two more
aloft with muskets, the rest to the guns, he changed the "grape" or
"canister" with which the guns were loaded in case of surprise, for
shot, cleared the decks, drew in ladders, and before the cavalry came
within range everything was ready for them. The oxen were always yoked
in order that Shard could manoeuvre his ship at a moment's notice.

When first sighted the cavalry were trotting but they were coming on
now at a slow canter. Arabs in white robes on good horses. Shard
estimated that there were two or three hundred of them. At sixty yards
Shard opened with one gun, he had had the distance measured, but had
never practised for fear of being heard at the oasis: the shot went

Shard had the range then and by the time the ten remaining guns of his
broadside were given the same elevation as that of his second gun the
Arabs had come to the spot where the last shot pitched. The broadside
hit the horses, mostly low, and ricochetted on amongst them; one
cannon-ball striking a rock at the horses' feet shattered it and sent
fragments flying amongst the Arabs with the peculiar scream of things

The broadside did not stop the Arabs nor even reduce their speed but
they crowded in closer together as though for company in their time of
danger, which they should not have done. They were four hundred yards
