16. The examination showed that the superior slope of the parapet was 
considerably damaged and altered in shape, and the interior crest on the 
proper left cut down 4 or 5 ft. deep, by 10 ft. wide. The terreplein was 
also covered with debris and splinters of shells. The experiment was 
renewed on the morning of the 4th of September, firing commencing at 
9.50 a.m., and continuing until the afternoon, with some slight cessations,

The parapet was examined several times during this fire, and photographed 
after the general rounds 512, 571, and at the conclusion. After the 51st 
round, on the 4th September (Gen. No. 512), the face of the work was 
considerably damaged and cut up; several large shell craters appeared, 
particularly on the proper left, where the breach was enlarged; the rest of 
the interior slope was not much damaged, but the terreplein of the work 
was covered thickly with splinters of shells, stones, and lumps of hard clay, 
which in many instances had penetrated for some distance into the bank 
behind. 
17. After the 110th round (Gen. No. 571), a photograph was taken of the 
interior. The damage done to the interior crest was not much increased. In 
front, the parapet had become an irregular heap of earth; the earth, however, 
was not so much displaced, the explosion of the shells throwing it up in a 
column, which fell down near the same spot from which it had been moved. 
The terreplein was covered with additional splinters and debris . 
After the 143rd round (Gen. No. 604), a short examination showed that 
a clear breach was made on the proper left, the depth of which was about 
4 ft. 9 in. 
18. The total number of live shells fired at the parapet on the 4th 
September, was as follows :— 
110-pr. 76 I 4<0-pr. 59 
70-pr. 15 | 20-pr. 15 
10-inch. 6 
Full charges were used with each gun, except the 70-pr., which fired 
12 rounds with 8 lbs. charge. 
The grand total of live shells fired at this parapet in the two days will 
therefore be:—■ 
110-pr. 97 J 20-pr. 15 
70-pr. 27 10-inch 6 
40-pr. 67 I 68 -pr. 12 
The examination at the conclusion of the practice showed the front of the 
parapet considerably disfigured; in fact, it was a mere shapeless mound of 
earth. The breach on the proper left was enlarged to about 33 ft. in width, 
by 5 ft. in depth, and the interior of the battery laid open.
