The first series of SAS Rogue Heroes re-told the story of the previously top secret origins of the Special Air Service, which was formed in North Africa in 1941 by Lieutenant-Colonel David Stirling.

It depicted the real-life events that were revealed at great length by historian Ben Macintyre in his 2016 book of the same name.

Stirling, who was described by Britain's most senior military officer as 'quite mad', is played by Connor, with Jack playing Mayne and Games of Thrones' Alfie Allen depicting Lewes.

The series was created by screenwriter Steven Knight, who was behind the hugely popular series Peaky Blinders.

'Convinced that traditional commando units don't work, he creates a radical plan that flies in the face of all accepted rules of modern warfare. 

'He fights for permission to recruit the toughest, boldest and brightest soldiers for a small undercover unit that will create mayhem behind enemy lines. 

'More rebels than soldiers, Stirling's team are every bit as complicated, flawed and reckless as they are astonishingly brave and heroic.' 

Connor's character, Colonel David Stirling, was a founding member of the SAS, a commando force that operated behind enemy lines during the North African campaign of the Second World War.

The SAS began with five officers and 60 other ranks when it was first conceived, and their first mission was a parachute drop supporting Operation Crusader in 1941 which ended in disaster, and may well be what Jack and Connor were filming.

During their first skirmish 22 men were killed or captured, however their second mission was a huge success after the SAS successfully destroyed 60 aircraft over three airfields.

Stirling was captured by enemy combatants in 1943 and Paddy Mayne, played by Jack, replaced him as commanding officer of the SAS, which was split into two factions the Special Raiding Squadron (SRS) and the Special Boat Section.
