He documented his experiences during and after the conflict in a book, co-written with his father, John Lawrence, entitled When the Fighting Is Over: A Personal Story of the Battle for Tumbledown Mountain and Its Aftermath.
Lawrence wrote about his experience in the Scots Guards at the Battle of Mount Tumbledown when, in his moment of victory on the eastern slopes, he was almost killed when a bullet fired by an Argentine sniper tore off the side of his head.
The Argentinian sniper (either Private Luis Jorge Bordón or Walter Ignacio Becerra, according to Argentine Second Lieutenant Augusto Esteban La Madrid[6] who clashed with Lawrence's platoon), armed with a FAL rifle, had helped cover the Argentinean retreat, firing shots at a Scout helicopter evacuating wounded off Tumbledown and injuring two men, before the Scots Guards mortally wounded him in a hail of gunfire.
[citation needed] His story was adapted into the BBC television drama film Tumbledown written by Charles Wood, directed by Richard Eyre and starring Colin Firth as Lawrence, which was viewed by more than 10 million people on its first showing.
[citation needed] In June 2022, Lawrence was featured in the documentary Our Falklands War: A Frontline Story that was shown on BBC2; where he recalls in detail the events that nearly cost him his life during the Battle of Mount Tumbledown.
