Other titles:RESERVED DEMOLITIONS [Alternative Title]
Summary: Dramatised Army Instructional film in which a retreating British Corps fighting a fictitious war withdraws across a river using two permanent bridges.
Description: The film shows the process by which orders are issued for the destruction of the bridges after all British units have crossed, including the delegation of authority to certain officers, stating who may give the executive order for the demolition and under what circumstances. The flexible nature of the system is further demonstrated when one bridge is destroyed by enemy air attack and demolition orders relating to the other are quickly changed. After the last British units have crossed, the bridge is blown up and the war continues. The technical aspects of bridge demolition are touched on briefly, but the focus is very much on the command, procedural and administrative functions necessary for the operation.
