Warrant Officer Class I Ernest Thomas “Bob” Lilley, MM, BEM 2MID 1SAS Original (Tobruk Four)
Ernest Thomas “Bob” Lilley (10 February 1914 – 14 August 1981) was a foundational British Army soldier and one of the original members of the Special Air Service (SAS) in the Second World War. A career soldier renowned for his toughness, courage, and exceptional service, Lilley helped shape the earliest unconventional tactics of the SAS and went on to serve with distinction through decades of conflict.

With the outbreak of the Second World War, Lilley’s service took him into the realm of elite forces. He transferred from the Guards to No. 8 Commando, participating in Layforce operations in the Mediterranean. In September 1941, he was selected by Lieutenant Colonel David Stirling as one of the first four men to form ‘L’ Detachment, Special Air Service Brigade, alongside Pat Riley, Jim Almonds, and Jim Blakeney — the group that would become famously known as the “Tobruk Four.”

Behind Enemy Lines Raids
Lilley participated in numerous deep penetration operations in North Africa, carrying out sabotage raids against Italian and German forces. These included destructive actions on airfields and supply points in and around Tobruk, El Agheila, Fuka, Benghazi, and other sectors where SAS raiders struck at Axis logistics and air power infrastructure.
Heroic Action & Survival
One well known SAS action involving Lilley occurred during a mission when he realized an explosive device was about to detonate inside an SAS truck. His swift warning saved the lives of comrades including David Stirling and Jock Lewes — moments later, the vehicle exploded where they had been moments before.
Lilley was recognized for his skill in close quarters combat and unconventional tactics, traits often mentioned in SAS accounts as part of the unit’s early traditions. In special forces circles, the term “a boblilley” has even been used informally to describe a quick, decisive hit and run style assault, reflecting his reputation for bold action.

Bob Lilley’s courage and service were recognised with several honours during and after the Second World War:
• Military Medal (MM): Awarded in November 1942 for bravery during a daring raid behind enemy lines when he was captured by an Italian guard, Lilley disagreed , strangled his guard and made good his escape.
• Mentioned in Despatches: Twice recognised for distinguished service.
• British Empire Medal (BEM): Awarded in 1952 for his services, including leadership and training roles after the war.
