Long Range Desert Group

Long Range Desert Group is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Long Range Desert Group rather than just read about it. In short: The Long Range Desert Group (LRDG) was a reconnaissance and raiding unit of the British Army during the Second World War. Originally called the Long Range Patrol (LRP), the unit was founded in Egypt in June 1940 by Major Ralph Alger Bagnold, acting under the direction of General Archibald Wavell.

Key takeaways

  • Long Range Desert Group belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Long Range Desert Group to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Long Range Desert Group from memory before moving on to harder problems.

Reference excerpt

The Long Range Desert Group (LRDG) was a reconnaissance and raiding unit of the British Army during the Second World War. Originally called the Long Range Patrol (LRP), the unit was founded in Egypt in June 1940 by Major Ralph Alger Bagnold, acting under the direction of General Archibald Wavell. Bagnold was assisted by Captain Patrick Clayton and Captain William Shaw. The majority of the men were from New Zealand, but they were soon joined by a few Southern Rhodesian and British volunteers, whereupon new sub-units were formed and the name was changed to the better-known Long Range Desert Group (LRDG). The LRDG never numbered more than 350 men, all of whom were volunteers. The LRDG was formed specifically to carry out deep penetration, covert reconnaissance patrols and intelligence missions from behind Italian lines, although they sometimes engaged in combat operations. Because the LRDG were experts in desert navigation, they were sometimes assigned to guide other units, including the Special Air Service and secret agents across the desert. During the Desert Campaign between December 1940 and April 1943, the vehicles of the LRDG operated constantly behind the Axis lines, missing a total of only 15 days during the entire period. Possibly their most notable offensive action was during Operation Caravan, an attack on the town of Barce and its associated airfield, on the night of 13 September 1942. However, their most vital role was the 'Road Watch', during which they clandestinely monitored traffic on the main road from Tripoli to Benghazi, transmitting the intelligence to British Army Headquarters. With the surrender of the Axis forces in Tunisia in May 1943, the LRDG changed roles and moved operations to the eastern Mediterranean, carrying out missions in the Greek islands, Italy and the Balkans. After the end of the war in Europe, the leaders of the LRDG made a request to the War Office for the unit to be transferred to the Far East to conduct operations against the Japanese Empire. The request was declined and the LRDG was disbanded in August 1945.

Formation Before the war, Major Ralph Bagnold learned how to maintain and operate vehicles, how to navigate, and how to communicate in the desert. On 23 June 1940 he met General Archibald Wavell, the commander of Middle East Command in Alexandria and explained his concept for a group of men intended to undertake long-range reconnaissance patrols to gather intelligence behind the Italian lines in Libya. General Wavell was familiar with desert warfare, having been a liaison officer with the Egyptian Expeditionary Force during the First World War, and he understood and endorsed Bagnold's suggested concept. Wavell assisted in equipping the force.

The unit, initially known as the No. 1 Long Range Patrol Unit (LRP), was founded on 3 July 1940. Bagnold wanted men who were energetic, innovative, self-reliant, physically and mentally tough, and able to live and fight in seclusion in the Libyan desert. Bagnold felt that New Zealand farmers would possess these attributes and was given permission to approach the 2nd New Zealand Division for volunteers; over half the division volunteered. Two officers and 85 other ranks including 18 administrative and technical personnel were eventually selected, coming mostly from the Divisional Cavalry Regiment and the 27th Machine-Gun Battalion. Once the men had been recruited, they started training in desert survival techniques and desert driving and navigation, with additional training in radio communications and demolitions. The LRP could initially form only three units, known as patrols, but a doubling of strength allowed the addition of a new Heavy Section. In November 1940, the name of the LRP was changed to the "Long Range Desert Group" (LRDG), and the New Zealanders were joined by volunteers from British and Southern Rhodesian regiments. The British volunteers, who came mostly from the Brigade of Guards and Yeomanry regiments, were incorporated into their own patrols. The original patrol unit consisted of two officers and 28 other ranks, equipped with a Canadian Military Pattern (CMP) Ford 15 Imperial hundredweight (cwt) truck and ten Chevrolet 30 cwt trucks. In March 1941 new types of trucks were issued and the patrol units were split into half-patrols of one officer and 15–18 men in five or six vehicles. Each patrol incorporated a medical orderly, a navigator, a radio operator and a vehicle mechanic, each of whom manned a truck equipped for their role.

Worked examples

Example 1 — a first encounter with Long Range Desert Group

Start with the simplest possible case. Write down what Long Range Desert Group claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Long Range Desert Group before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Long Range Desert Group ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Long Range Desert Group

In research
Long Range Desert Group appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Long Range Desert Group in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Long Range Desert Group is common in secondary-school and first-year university syllabi. It links to neighbouring topics Army reconnaissance units and formations, Desert warfare, Military history of New Zealand during World War II, so understanding it makes those chapters shorter.
In everyday life
Look for Long Range Desert Group outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
