Railway bridge on road from Harbonnieres to Rosieres en Santerre. Musical Box was one of the 72 Whippets sent into action that day (Aug 11th 1918) and was crewed by Lieutenant Clement B. Arnold, Private Christopher Ribbans (Gunner) and Private William J Carnie (Driver) of the 6th Battalion Tank Corps. They started their attack near Villers Bretooneaux and went eastwards through Gullaucourt and Arnold noticed the canopy of a truck heading their way. They then hid up and waited for the lorry to come over the rise of the bridge. Here Arnold shot the driver and the lorry crashed into a ditch on the right.
