Question: What year did the campaign end in which Wheaton commanded a brigade in 1864? Passage 1:Paul was a McDonald's All-American in high school. He attended Wake Forest University for two years of college basketball, where he helped the Demon Deacons achieve their first-ever number one ranking. He was selected fourth overall in the 2005 NBA draft by the New Orleans Hornets, where he developed into one of the league's premier players, finishing second in NBA Most Valuable Player Award voting in 2008. During the 2011 offseason, Paul was traded to the Los Angeles Lakers, only for the transaction to be controversially voided by the NBA. Later that summer, he was dealt to the Los Angeles Clippers instead. Behind Paul's playmaking, the Clippers developed a reputation for their fast-paced offense and spectacular alley-oop dunks, earning them the nickname "Lob City". In 2017, he was traded to the Houston Rockets, and helped the team win a franchise-record 65 games in his debut season. He was traded to the Oklahoma City Thunder for Russell Westbrook on July 16, 2019.
Passage 2:Guardigli was born in Ravenna. At 18 he enrolled in and attended the School of Fine Arts of Ravenna. During World War II he was drafted and served from 1943 until 1946 in the Regia Marina (Italian Royal Navy) at La Spezia). After the war he returned to the School of Fine Arts, receiving his diploma in 1948. He enrolled in the School of Painting and Mosaics, also in Ravenna, graduating in 1951. From 1951 to 1955 he worked with the Gruppo mosaicisti of Ravenna and restored many mosaics. Also in 1951, at the end of November, he arrived in Paris to teach at the Ecole d'Art Italien (School of Italian Art) as an assistant to the painter Gino Severini, founder and director of the school. Together with another mosaicist, his fellow Ravennan Lino Melano, he executed mosaic works for artists including Fernand Leger, Georges Braque, Marc Chagall, Jean Bazaine, and Raoul Ubac. He collaborated also on the mosaic for the facade of the Musee national Fernand Leger in Biot (Alpes-Maritimes). In 1960 he executed, at the Colombe d'Or of Saint-Paul-de-Vence, a mosaic by the painter Georges Braque. From 1961 he had a studio in the artists' residence La Ruche at 2, passage de Dantzing in Paris, the place described by Lorenzo Viani in the book Parigi 1925 (Paris 1925), published by Fratelli Treves. In 1962, in another collaboration with Braque, he created the famous long fish tank of the Fondation Maeght in St Paul de Vence. His collaborations with many illustrious artists continued; the last was Jean-Michel Folon. Many of his personal works in painting and mosaics are in prominent private and public collections. The latter portion of his life was spent in an old people's rest home in Paris, where he died in 2008.
Passage 3:Wheaton remained in command of the brigade during Lt. Gen. Ulysses S. Grant's Overland Campaign in 1864, as well as during the subsequent Siege of Petersburg. His men were hurried by train to Washington, D.C., in time to help repel Jubal Early's raid on the capital. During the ensuing operations in the Shenandoah Valley, under Maj. Gen. Philip Sheridan, Wheaton was promoted to command of the first division after Brig. Gen. David Allen Russell was killed at the Third Battle of Winchester. His division fought well in subsequent battles. In the Battle of Sailors Creek Virginia, on April 6, 1865, his division captured Confederate Major General George Washington Custis Lee, son of Robert E. Lee. After the return of VI Corps to the Petersburg front, Wheaton earned the brevet rank of major general in the volunteer army and was brevetted colonel in the regular services.
