Distinguished Service Order in the context of "Frederick John Dealtry Lugard"

Nicholas Geoffrey Lemprière Hammond, CBE, DSO, FBA (15 November 1907 – 24 March 2001) was a British historian, geographer, classicist and an operative for the British Special Operations Executive (SOE) in occupied Greece during the Second World War.

Hammond was seen as the leading expert on the history of ancient Macedonia. His trilogy, A History of Macedonia, has been described as the "most celebrated (and partly irreplaceable) work" on the subject. Additionally, he was recognised for his meticulous research on the geography, historical topography and history of ancient Epirus.

Lieutenant-General Arthur Ernest Percival, CB, DSO & Bar, OBE, MC, DL (26 December 1887 – 31 January 1966) was a British Army officer. He saw service in the First World War and built a successful military career during the interwar period, but is best known for his defeat in the Second World War, when Percival commanded British Commonwealth forces during the Malayan campaign, which culminated in a catastrophic defeat at the Battle of Singapore.

Percival's surrender to the invading Imperial Japanese Army, which was the largest of its kind in British military history, significantly undermined Britain's prestige and military position in East Asia. Some historians, such as Sir John Smyth, have argued that under-funding of British Malaya's defences and the inexperienced, under-equipped nature of the Commonwealth forces in Malaya, not Percival's leadership, were ultimately to blame for the defeat.

Field Marshal Bernard Law Montgomery, 1st Viscount Montgomery of Alamein, KG, GCB, DSO, PC, DL (17 November 1887 – 24 March 1976), nicknamed "Monty", was a senior British Army officer who served in the First World War, the Irish War of Independence and the Second World War.

Montgomery first saw action in the First World War as a junior officer of the Royal Warwickshire Regiment. At Méteren, near the Belgian border at Bailleul, he was shot through the right lung by a sniper during the First Battle of Ypres. On returning to the Western Front as a general staff officer, he took part in the Battle of Arras in April–May 1917. He also took part in the Battle of Passchendaele in late 1917 before finishing the war as chief of staff of the 47th (2nd London) Division. In the inter-war years he commanded the 17th (Service) Battalion, Royal Fusiliers and, later, the 1st Battalion, Royal Warwickshire Regiment before becoming commander of the 9th Infantry Brigade and then general officer commanding (GOC), 8th Infantry Division.

Alfred Duff Cooper, 1st Viscount Norwich, GCMG, DSO, PC (22 February 1890 – 1 January 1954), known as Duff Cooper, was a British Conservative Party politician and diplomat who was also a military and political historian and writer.

First elected to Parliament in 1924, he lost his seat in 1929 but returned to Parliament in the 1931 Westminster St George's by-election, which was seen as a referendum on Stanley Baldwin's leadership of the Conservative Party. He later served in the Cabinet as Secretary of State for War and First Lord of the Admiralty. He resigned from the cabinet over the Munich Agreement of 1938.

Kenneth Essex Edgeworth DSO MC (26 February 1880 – 10 October 1972) was an Irish army officer, engineer, economist and independent theoretical astronomer. He was born in Street, County Westmeath. Edgeworth is best known for proposing the existence of a disc of bodies beyond the orbit of Neptune in the 1930s. Observations later confirmed the existence of the Edgeworth-Kuiper belt in 1992. Those distant solar system bodies, including Pluto, Eris and Makemake, are now grouped into the Edgeworth-Kuiper belt, or Kuiper belt.

Field Marshal William Edmund Ironside, 1st Baron Ironside, GCB, CMG, DSO (6 May 1880 – 22 September 1959) was a senior officer of the British Army who served as Chief of the Imperial General Staff during the first year of the Second World War.

Ironside joined the Royal Artillery in 1899, and served throughout the Second Boer War. This was followed by a brief period spying on the German colonial forces in German South West Africa. Returning to regular duty, he served on the staff of the 6th Infantry Division during the first two years of the First World War, before being appointed to a position on the staff of the newly raised 4th Canadian Division in 1916. In 1918, he was given command of a brigade on the Western Front. In 1919, he was promoted to command the Allied intervention force in northern Russia. Ironside was then assigned to an Allied force occupying Turkey, and then to the British forces based in Persia in 1921. He was offered the post of the commander of British forces in Iraq, but was unable to take up the role due to injuries in a flying accident.

Lieutenant-General Bernard Cyril Freyberg, 1st Baron Freyberg, VC, GCMG, KCB, KBE, DSO & Three Bars, KStJ (21 March 1889 – 4 July 1963) was a British-born New Zealand soldier and Victoria Cross recipient, who served as the 7th governor-general of New Zealand from 1946 to 1952 - the first to have been raised and educated in New Zealand.

Freyberg served as an officer in the British Army during the First World War. He took part in the beach landings during the Gallipoli campaign and was the youngest general in the British Army during the First World War, later serving on the Western Front, where he was decorated with the Victoria Cross and three Distinguished Service Orders, making him one of the most highly decorated British Empire soldiers of the First World War. He liked to be in the thick of the action: Winston Churchill called him "the Salamander" due to his ability to pass through fire unharmed.

A medal bar or medal clasp is a thin metal bar attached to the ribbon of a military decoration, civil decoration, or other medal. It most commonly indicates the campaign or operation the recipient received the award for, and multiple bars on the same medal are used to indicate that the recipient has met the criteria for receiving the medal in multiple theatres.

When used in conjunction with decorations for exceptional service, such as gallantry medals, the term "and bar" means that the award has been bestowed multiple times. In the example, "Group Captain Leonard Cheshire, VC, OM, DSO and two bars, DFC", "DSO and two bars" means that the Distinguished Service Order was awarded on three occasions. A British convention is to indicate bars by the use of asterisks; thus, DSO** would denote a DSO and two bars.

General Sir Archibald James Murray, GCB, GCMG, CVO, DSO (23 April 1860 – 21 January 1945) was a British Army officer who served in the Second Boer War and the First World War. He was chief of staff to the British Expeditionary Force (BEF) in August 1914 but appears to have suffered a physical breakdown in the retreat from Mons, and was required to step down from that position in January 1915. After serving as Deputy Chief of the Imperial General Staff for much of 1915, he was briefly Chief of the Imperial General Staff from September to December 1915. He was subsequently Commander-in-Chief of the Egyptian Expeditionary Force from January 1916 to June 1917, in which role he laid the military foundation for the defeat and destruction of the Ottoman Empire in the Arabian Peninsula and the Levant.
