While the battle was in progress on John's island, a Brooke gun, brought to Battery Pringle, drove the enemy's wooden boats down stream. An attempt of the enemy to float fire rafts with the tide against the Stono bridge was defeated by Lieutenant Smith, with a detachment of the naval battalion, who brought them to shore, and a second barge attack on Fort Johnson was repulsed, the garrison being aided by Le Gardeur's battery and a company of marines. On the 11th the enemy disappeared.

In his detailed report, Gen.

That it failed is due, under Providence, to the gallantry and good conduct of our officers and men.’ His aggregate of losses was 33 killed and 96 wounded.

The part of this campaign which fell upon Fort Sumter was a fierce bombardment by day and night, in which from July 7th to July 31st inclusive, 7,000 shot and shell took effect. On the 7th the flag was cut down three times.
