Why did Paddy Mayne leave the SAS?

When the SAS was disbanded in 1945, Mayne lost the unit that had defined him. According to the National Army Museum, he returned to civilian life and resumed his legal studies. But the transition was far from smooth.

Post-war SAS disbandment and return to civilian life

  • The SAS was officially disbanded in October 1945, leaving Mayne without a command.
  • He went back to studying law, having qualified as a solicitor before the war (Wikipedia).

Alcohol and discipline issues

  • Mayne had a reputation for heavy drinking and insubordination, even during his active service.
  • Biographers note that his post-war behaviour grew more erratic, with several reported incidents of public drunkenness.

Mayne’s own account versus official records

  • He resigned his commission in 1946, citing a desire to return to civilian life.
  • Some sources claim he was pushed out due to his disciplinary record; others say he left voluntarily.
Bottom line: Mayne left the SAS after it was disbanded, but the exact mix of personal choice and institutional pressure remains disputed. For historians, the lack of a definitive explanation is the key gap.

Were David Stirling and Paddy Mayne friends?

Their partnership was the engine of the early SAS, but it was never simple. Six facts, one pattern: the closeness that made them effective also bred resentment.

Early partnership in the SAS

  • Stirling recruited Mayne after seeing him lead a raid from a prison cell — a now-famous origin story recorded by the National Army Museum.
  • They worked closely in North Africa, with Mayne leading the most dangerous missions.

Tensions and falling out in 1943

  • When Stirling was captured in January 1943, Mayne took command of 1st SAS Regiment.
  • According to the SAS: Rogue Heroes Wiki, Mayne resented Stirling’s promotion and public acclaim, and their leadership styles clashed.

Later accounts from both sides

  • After the war, their friendship cooled but they remained in contact.
  • Stirling later praised Mayne’s bravery in interviews, calling him “the finest soldier I ever met” (BBC).
The paradox

Stirling owed his success to Mayne’s battlefield brilliance, but that very brilliance made Mayne impossible to manage. The friendship was real, but it was also a competition.

Bottom line: Stirling and Mayne were close partners who grew apart. The trade-off: the SAS gained its most fearsome fighter, but lost the easy camaraderie of its early days.

Did Paddy Mayne consider himself Irish?

Mayne’s national identity is one of the most debated aspects of his legacy. The evidence points both ways.

Upbringing in Northern Ireland

  • Born in Newtownards, County Down, he grew up in a unionist family that supported the British connection.
  • He attended Regent House Grammar School in Newtownards.

Identity as a British Army officer

  • He served in the British Army and flew the Union Flag on his car, according to The Irish Post.
  • His nickname “Paddy” was a common British Army label for Irish soldiers, which he reportedly accepted.
