Question: Which of the Secretaries that served in the Civil War held the post of Secretary longer? Passage 1:According to Orwell, the fable reflects events leading up to the Russian Revolution of 1917 and then on into the Stalinist era of the Soviet Union. Orwell, a democratic socialist, was a critic of Joseph Stalin and hostile to Moscow-directed Stalinism, an attitude that was critically shaped by his experiences during the Spanish Civil War. The Soviet Union, he believed, had become a brutal dictatorship, built upon a cult of personality and enforced by a reign of terror. In a letter to Yvonne Davet, Orwell described Animal Farm as a satirical tale against Stalin (""), and in his essay "Why I Write" (1946), wrote that Animal Farm was the first book in which he tried, with full consciousness of what he was doing, "to fuse political purpose and artistic purpose into one whole".
 Passage 2:Frank Alberry, DCM (29 September 1892 – 23 January 1968) was an Australian soldier and airman who had a varied military career. Born in Hobart, he served in the Welch Regiment of the British Army before the First World War, but deserted. He joined up again in the early days of the First World War, and went on to serve with the 8th Battalion of the Australian Imperial Force. After service at Gallipoli, he joined the British Expeditionary Force in France. He won a Distinguished Conduct Medal at the Battle of Pozières, but lost a lower leg in the process. Alberry took the extraordinary step of personally petitioning King George V for permission to transfer to the Flying Corps, and subsequently became a flying ace credited with seven aerial victories. Alberry returned to service during the Second World War as a recruiter.
 Passage 3:A position of great trust and responsibility, the Senate secretaryship has been held by a long line of distinguished individuals. Samuel Allyne Otis, the first secretary of the Senate, had previously been speaker of the Massachusetts legislature and a member of the Continental Congress. Otis held the post of secretary for twenty-five years, never missing a day that the Senate was in session. General Anson McCook of New York, a former House member and one of the "Fighting McCooks" of the Civil War, served as secretary, as well as a former Confederate general and Congressman, William R. Cox of North Carolina. In addition, two former U.S. senators, Charles Cutts of New Hampshire and Walter Lowrie of Pennsylvania, have later served as secretary. Other former House members who have held the post include Charles G. Bennett (NY). During the Ninety-ninth Congress (1985–1987), Jo-Anne Coe became the first woman to serve as secretary.
