From The Story of the 2/4th Oxfordshire and Buckinghamshire Light Infantry, by Captain G. K. Rose KC (Oxford: B.H. Blackwell, 1920)
Two nights afterwards, when the wind luckily was again from the right direction, the raid was carried out. The Germans, of whom some were found in gas-helmets, had no inkling of our plan. B Company, though they missed the gap through the enemy’s wire, entered the trenches without opposition and captured a machine-gun which was pointing directly at their approach but never fired. Wallington, the officer in command of the storming party, killed several Germans. As often, there was difficulty in finding the way back to our lines; in fact, Moberly, the commander of the raid, after some wandering in No-Man’s-Land, entered the trenches of a Scotch division upon our right. His appearance and comparative inability to speak their language made him a suspicious visitor to our kilted neighbours. Moberly rejoined his countrymen under escort.
