Passage: When the American Civil War began, Weitzel was assigned to construct defenses, including in Cincinnati and Washington, as well as for George McClellan in the Army of the Potomac in late 1861. He was then attached to the staff of Major General Benjamin F. Butler as chief engineer of the Department of the Gulf. When Union troops captured New Orleans, Weitzel became assistant military commander and acting mayor. He was promoted to brigadier general in August 1862 and two months later routed a large force of the enemy at Labadieville, Louisiana, which earned him a brevet promotion to major in the Regular Army. Weitzel commanded a brigade in the XIX Corps advancing in Major General Nathaniel P. Banks's operations in western Louisiana during April and May 1863, which led to the siege of Port Hudson. Weitzel was later brevetted lieutenant colonel in the Regular Army, "for gallant and meritorious services at the siege of Port Hudson," which fell on July 9, 1863, days after Vicksburg, Mississippi, about 120 miles upriver, the last Confederate stronghold on the great Mississippi, had fallen. Together those successful sieges and the continuing blockage of Southern ports completed the Anaconda Plan.

Passage: Strutt was baptised at Springfield, Essex, on 26 February 1762, the second son of John Strutt, of Terling Place, Essex, by Anne, daughter of the Rev. William Goodday of Maldon. Entering the army in 1778, he joined his regiment, the 61st, at Minorca. Later he was appointed to a company in the 91st, and took part in the defence of St. Lucia. In 1782, having exchanged into the 97th, he served at the siege of Gibraltar. On the signing of the preliminaries of peace he purchased a majority in the 60th regiment, and, being placed on half-pay, visited several German courts. In 1787 he was sent with his regiment to the West Indies, where he took an active part in military affairs. Succeeding to a lieutenant-colonelcy by special command of George III, he was removed to the 54th, and went with the army of Lord Moira to Flanders. In 1794 he bore a very distinguished part against the French at Tiel, going through much hard fighting. On his return he was sent to St. Vincent, where he was raised to the rank of brigadier-general. In January 1796, with two hundred men, he attacked a force of twelve hundred, being himself thrice wounded, and losing his right leg. On his return to England he was received with marked favour by the king, and on 23 February 1796 was made deputy governor of Stirling Castle, afterwards serving upon the staff in Ireland. On 23 June 1798 he was raised to the rank of major-general, and on 13 May 1800 he was, as a reward for his services, appointed to the sinecure office of governor of Quebec, and he held that post until his death. He died at Tofts, Little Baddow, Essex, on 5 February 1848, having seen an exceptional amount of military service, both at home and abroad.

Passage: Upon completion of his degree studies at Brera in early 1939, he was drafted by the Italian military for service in World War II. He was deployed to Slovenia, and later to Sicily and Albania, and when his tours of duty were complete, he would participate in art exhibitions. He continued to paint during his service, even when on the front lines, committing to canvas images of "dramatic testimonials" considered prohibited, such as Albanian villages razed by Italian troops. At the end of the war, he also began working on frescoes, glass art, and mosaic art. In 1942, he exhibited works at the Venice Biennale and at the Mostra degli artisti in armi ("Artists in arms") exhibit at the Palazzo delle Esposizioni in Rome, where he presented three watercolours and seven pen drawings, all having a war theme. By this time, he was a sergeant for the Genio Ferrovieri. His first personal exhibition occurred in 1943 and was presented by Raffaello Giolli at the Galleria La Rotonda in Bergamo. He dedicated himself to teaching and the creation of works of sacred art in 1945. He would exhibit at the Venice Biennale again in 1948, 1950, 1956, and 2011, and was invited to exhibit at the Rome Quadriennale in 1952.
