The story of an American submarine that sailed through a Japanese Naval Base to rescue six Allied commandos who found themselves stranded behind enemy lines in Borneo

Documentary series exploring the use of submarines in the Second World War, beginning with the story of a German U-boat that escaped a barrage of underwater bombs

The USS Lexington birthed naval aviation and was victorious in the first carrier-to-carrier battle during the Second World War. Hours later, it erupted in flames due to enemy fire. Now, after 80 years, the Petrel crew hopes to spot the wreck and the planes that went down with her

The Petrel team searches for the aircraft carrier USS Hornet. The Doolittle Raid was launched off her deck to avenge Pearl Harbor, but the vessel was sunk just six months later

Historian Suzannah Lipscomb and journalist Joe Crowley investigate stories connected to the Tower of London, looking at the contrasting fates of three people imprisoned in the Tower of London for treason. They examine what happened to Jesuit priest Fr John Gerard after he was accused of being sent by the pope to overthrow Elizabeth I, and look at the cases of Gunpowder Plot conspirator Guy Fawkes and German spy Josef Jakobs, who was captured in 1941 after breaking his ankle while parachuting into England on a mission

Tudor historian Suzannah Lipscomb and journalist Joe Crowley investigate the history of the Tower of London, examining stories that challenge accepted beliefs about the infamous prison using original historical sources and dramatic reconstructions. Here they consider why it took executioner John Ketch five blows to decapitate the Duke of Monmouth in July 1685, and examine whether former inmate Lady Jane Grey had a legitimate claim to the English throne. They also look into how a ragtag gang managed to breach its defences during the Peasants' Revolt in June 1381 and killed Simon of Sudbury, the Archbishop of Canterbury

Suzannah Lipscomb and Joe Crowley examine the evidence and report on the intrigues that led to three royal deaths, detailing the sometimes salacious accusations levelled at Anne Boleyn, Catherine Howard and Lady Arabella Seymour. Henry VIII's chief minister Thomas Cromwell informed the monarch of gossip about Anne and court musician Mark Smeaton, but allegations at her public trial included adultery with five men, incest with her brother George and treason. Rumours of relationships with distant cousin Francis Dereham and Thomas Culpeper led to Catherine Howard's execution, while Lady Arabella, a serious threat to the ruling Stuart dynasty, is thought to have committed suicide against a backdrop of a cross-dressing noblewoman and two escapes from the Tower
