During World War II the extensive tunnels within the Rock of Gibraltar were further extended. This included a tunnel that joined these barracks to the Gun Operations Room. This operations room was well connected to other tunnels, meaning that it was possible to travel to the north face of Gibraltar whilst remaining within the rock. Some of this journey would be down the Great North Road where you could take a ride on a passing truck. The tunnel between the operations room and the barracks was closed following a number of falls including one that killed a civilian visitor.[3]
Lieutenant Colonel Mohamed Amekrane who had ordered an unsuccessful coup against King Hassan II of Morocco, was once imprisoned at Lathbury Barracks.[4] The British Government extradited him to Morocco where he was executed. The British Government later made an out of court settlement in 1972 with his widow Malika Amekrane to avoid a case at the European Commission of Human Rights regarding his extradition.[5]
