On examining the wall there was a practicable breach of 14 ft. wide, and 
the buttresses were much injured.

The splinters of the shells being inconvenient to the men in the 400 yds. 
battery, the bursting powder of the shells was considerably reduced. 
3. On the 6th of August the firing recommenced from 
Eight 68-pr. carronades at 500 yds. 
Two 8-in. iron howitzers 400 „ 
Four 10-in. do 400 „ 
The fire of these pieces was intended to be directed towards the more 
effectual opening of the breach and the more complete destruction of the 
buttresses. 
Fifty rounds per piece were fired in two hours, when the breach was 
examined and found to be complete in every respect, and the buttresses 
to be in the ruinous state more clearly shown by the darker shade of fig. 1.
