Question: In what conflict was the screenwriter of I, Claudius?

full_context: Document 1: Jethro Sumner: Sumner was named the commanding officer of the 3rd North Carolina Regiment of the North Carolina Line, a formation of the Continental Army, in 1776, and served in both the Southern theater and Philadelphia campaign. He was one of five brigadier generals from North Carolina in the Continental Army, in which capacity he served between 1779 and 1783. He served with distinction in the battles of Stono Ferry and Eutaw Springs, but recurring bouts of poor health often forced him to play an administrative role, or to convalesce in North Carolina. Following a drastic reduction in the number of North Carolinians serving with the Continental Army, Sumner became a general in the state's militia but resigned in protest after the North Carolina Board of War awarded overall command of the militia to William Smallwood, a Continental Army general from Maryland. After the end of the war in 1783, Sumner helped to establish the North Carolina Chapter of the Society of the Cincinnati, and became its first president. He died in 1785 with extensive landholdings and 35 slaves.
Document 2: The Greatest Story Ever Told: The Greatest Story Ever Told is a 1965 American epic film produced and directed by George Stevens. It is a retelling of the story of Jesus Christ, from the Nativity through to the Ascension. This film is notable for its large ensemble cast and for being the last film appearance of Claude Rains.
Document 3: Oskar Maria Graf: On 1 December 1914, he was drafted for military service. A year later, in 1915, he published his first story, in the magazine Die Freie Straße ["Free street"]. In 1916, Graf was nearly court-martialed for refusing a command. However, after a ten-day hunger strike, he was sent instead to a psychiatric hospital and later discharged from the military.
Document 4: I, Claudius (film): I, Claudius is an unfinished 1937 film adaptation of the novels "I, Claudius" (1934) and "Claudius the God" (1935) by Robert Graves. Produced by Alexander Korda, the film was directed by Josef von Sternberg, with Charles Laughton in the title role. The production was dogged by adverse circumstances, culminating in a car accident involving co-star Merle Oberon that caused filming to be ended before completion. Footage from the production was incorporated into a 1965 documentary on the making of the film, "The Epic That Never Was".
Document 5: Village of the Damned (1960 film): The film was originally an American picture, to be filmed at the Metro - Goldwyn - Mayer studios in Culver City, California when preproduction began in 1957. Ronald Colman was contracted for the leading role, but MGM shelved the project, bowing to pressure from religious groups that objected to the sinister depiction of virgin birth. Colman died in May 1958 -- by coincidence, his widow, actress Benita Hume, married actor George Sanders in 1959, and Sanders took the role meant for Colman.
Document 6: In Flanders Fields: ``In Flanders Fields ''is a war poem in the form of a rondeau, written during the First World War by Canadian physician Lieutenant - Colonel John McCrae. He was inspired to write it on May 3, 1915, after presiding over the funeral of friend and fellow soldier Lieutenant Alexis Helmer, who died in the Second Battle of Ypres. According to legend, fellow soldiers retrieved the poem after McCrae, initially dissatisfied with his work, discarded it.`` In Flanders Fields'' was first published on December 8 of that year in the London magazine Punch.
Document 7: J. C. Dunn: Dunn, who had previously served in South Africa, was Regimental Medical Officer for the Royal Welch Fusiliers during World War I, and is mentioned in the memoirs of both Robert Graves and Siegfried Sassoon. Dunn wrote of his official role that: "The first duty of a battalion medical officer in War is to discourage the evasion of duty ... not seldom against one's better feelings, sometimes to the temporary hurt of the individual, but justice to all other men as well as discipline demands it."
Document 8: Somerset: Many Somerset soldiers died during the First World War, with the Somerset Light Infantry suffering nearly 5,000 casualties. War memorials were put up in most of the county's towns and villages; only nine, described as the Thankful Villages, had none of their residents killed. During the Second World War the county was a base for troops preparing for the D-Day landings. Some of the hospitals which were built for the casualties of the war remain in use. The Taunton Stop Line was set up to repel a potential German invasion. The remains of its pill boxes can still be seen along the coast, and south through Ilminster and Chard.
Document 9: Ossessione: Visconti adapted the script with a group of men he selected from the Milanese magazine "Cinema". The members of this group were talented filmmakers and writers and played a large role in the emerging neorealist movement: Mario Alicata, Gianni Puccini, Antonio Pietrangeli and Giuseppe De Santis. When "Ossessione" was completed and released in 1943, it was far from the innocent murder mystery the authorities had expected; after a few screenings in Rome and northern Italy, prompting outraged reactions from Fascist and Church authorities, the film was banned by the Fascist government reestablished in the German occupied part of Italy after the September 1943 armistice. Eventually the Fascists destroyed the film, but Visconti managed to keep a duplicate negative from which all existing prints have been made. After the war, "Ossessione" encountered more problems with mass distribution, this time in the United States. As a result of the wartime production schedule, Visconti had never obtained the rights to the novel and Metro-Goldwyn Mayer began production on another version of the film, directed by Tay Garnett ("The Postman Always Rings Twice", 1946), while the Fascist ban on Visconti's work was still in effect.
Document 10: Clive of India (film): Clive of India is a 1935 American historical biographical film starring Ronald Colman about the life of Robert Clive. It was written by R.J. Minney and W. P. Lipscomb and directed by Richard Boleslawski. Colin Clive, who appears in the film, was a descendant of Clive.
Document 11: Frederick Fryer: He served in the Second Boer War and the First World War, commanding his regiment and two mounted brigades. In later life he became a Deputy Lieutenant of Dorset and a Justice of the Peace.
Document 12: John Neville Manners: John Neville Manners (6 January 1892 – 1 September 1914) played cricket for Eton College in Fowler's match in 1910, and died in the early weeks of the First World War on the retreat from Mons. He was immortalised in poem LIV of "The Muse in Arms" by William Grenfell (brother of Julian Grenfell) entitled "To John".
Document 13: Number 111 (1919 film): Number 111 (Hungarian: A 111-es) is a 1919 Hungarian silent thriller film directed by Alexander Korda and starring Gábor Rajnay, María Corda and Gyula Bartos. The film was based on a novel by Jenő Heltai. It was Korda's final Hungarian film before he went into exile in Austria during the White Terror. The film was remade in 1938.
Document 14: James Youll Turnbull: He was a sergeant in the 17th Battalion (Glasgow Commercials), The Highland Light Infantry, British Army during the Battle of the Somme in First World War. On 1 July 1916, Turnbull was awarded the VC for his actions at Leipzig Salient, Authuille, France, where Turnbull's party captured a post of apparent importance, and defended it "almost single-handed[ly]". Later in the day he was killed while engaged in a bombing counter-attack. He was 32 years old.
Document 15: A Touch of Murder: A Touch of Murder is the first episode in the BBC drama serial "I, Claudius", based on the novels by Robert Graves. It was first broadcast on 20 September 1976 on BBC 2, in a two-hour special, along with the second episode "Family Affairs", and subsequent DVD and VHS releases put the two episodes together. It first aired at 9:00 pm and finished at 9:50, with the next episode straight after, and was later repeated on 25 September at 10:20 pm.
