Captain Brett Crozier: Maverick navy captain on leadership and loyalty

He was commended and condemned in equal measure, but his decision to fight for his troops ultimately saw him walk the plank. In 2020, Captain Brett Crozier disembarked the US Navy's most powerful aircraft carrier for the last time - relieved of duty after pleading with superiors to protect his sailors from Covid-19. As the virus swept through the ship, his letter begging for help hit the headlines. Two years later he retired. In his new book, 'Surf when you can' he reflects on his life, his work, and that career defining moment.
