1180 Struck the top plate 2' from the 
right side and 7*5 // from the bot¬ 
tom, nearly in line with one of the 
ribs, punching out a piece of plate 
7-75" diameter; the hole was 
stopped up with splinters of the 
backing; three bolts in the lower 
row, one in the centre, and two in 
the upper row of this plate were 
started from-75" to 1" (one of the 
bolts which had started in the 
lower row was at a distance of 4 / 5 // 
from the point of impact), and the 
plate had started out from the 
backing 1 , 25 // on the right side; at 
the top the front baulk of the tim¬ 
ber backing was blown out for a 
length of 2', and the skin was 
driven back -875 of an inch for 
the same length. At the back 
a large irregular breakage of 
inner skin ; a piece of shell stick¬ 
ing in the hole shutting out day¬ 
light till removed. Inner diameter 
of hole about 10"; wood backing 
closed up considerably on path of 
shot; one rib broken and driven 
out, together with rent skin, about 
1 '; general bulge over a surface of 
4' x 4'. 
The shell exploded further forward this time, blackening the sidle of chamber and roof (corresponding 
to “upper deck”) with bursting charge, and had evidently been diverted by striking in the line of 
the rib. Many (46) pieces of shell and inner skin of ship scattered about the interior. One piece 
of the former sticking in “ upper deck,” fragments had struck in every direction, in this instance, 
as far laterally as they could go (about 5' 6"). The butt of the shell remained in the hole and was 
taken out from the front. 
The shell broke into thirteen large and six small pieces; fragments picked up inside :—six large 
and six small bolt-heads, seven rivets, three washers, and five pieces of plate and skin, including the 
large piece punched out.

1227 Struck the centre plate 5' from the 
right side and 6" from the top, 
partly on a bolt, making an indent 
of 2-3", and forcing in the plate 
at the top side for a length of 5', 
to a depth of 3" at the deepest 
point; a crack 11" long extended 
from the top of the plate through 
a bolt-hole at a point 1' 2" from 
impact, also a crack 8" long from 
the top of the plate, through a 
bolt-hole, at a distance of 1' 4" 
„ ' the plate buckled ’6" at the right side; the shot broke up. At the back:—one 
vertical rib broken and one angle iron cracked. Six bolt and rivet heads broken off, at distances 
from point struck varying from 6" to 4'. 
The shell broke into seven large pieces and a great many very small ones; fragments :—three large 
and three small bolt-heads, one rivet, two pieces of skin, and one piece of rib.
