Plugged shell not as effective apparently as fuzed shell. Action of 
shell with time fuzes was varied; some appeared to hurst on impact, 
with others the action was delayed; the latter was most effective. The 
chances of delayed action appeared to he greater when the fuze was 
unhored. 
Percussion fuzes were apparently the most effective for the work 
required. 
Steady firing from flank to flank gave better results than salvos. 
Shell filled with sand had little or no effect, the penetration was from 
17 to 30 inches. 
Breaching operations were begun about half-way up the wall, the 
height was slightly raised afterwards, owing to accumulated debris. 
Daylight was seen after a salvo constituting the 88th and 93rd round. 
The 102 nd round completed the breach, but it was not practicable for 
infantry. After the conclusion of the practice the breach was 14 ft. 
wide, by 5 ft. deep. 20 to 30 rounds would have made the breach 
practicable.
