| They were to carry 6-feet tubes full of ammonal for blowing gaps in the wire. |
| The ammonal was discharged successfully, but the results were disappointing. |
| The first party found some thick wire, placed their ammonal tubes and successfully blew several gaps. |
| Several dug-outs were bombed, and in some cases set on fire, one being blown up by the Royal Engineers with an ammonal tube. |
| A time came when the gun-cotton and gelignite got scarce, and a powder explosive called ammonal had to be used. |
| We entered the crater immediately after it was blown, placed another charge of 200 pounds of ammonal, and blew it. |
