As the crew of the Black Thorn indulged in laughter, the deck of the Beagle was still a hive of hurrying activity.
Colonel Fitzroy, while observing the course of the Barbary pirate ship through his telescope, ordered an adjustment of the cannon positions.
"Set the range! Elevation 30 degrees, 15 degrees east by south, four shots, fire in unison!"
The thunderous roar of the cannons could be heard, causing a series of splashes on the sea surface. The Barbary pirate ship was hit in two places, but the damage was all above the waterline and did not affect its mobility.
But as soon as the barrage from the Beagle ended, the Barbary pirates' retaliation came swiftly.
They unveiled six guns in a row, firing fiercely at the Beagle.
With a loud boom, wood splinters flew all over the deck and smoke billowed.
