Teacher: Now, understand the problem? Solve this instance: Question: Who commanded the 32nd Virginia Volunteer Infantry Regiment when Goggin joined the Confederacy? Passage 1:In 1861, Goggin moved back to Virginia, entering the Confederate States Army on July 1, 1861 as a major in the 32nd Virginia Volunteer Infantry Regiment where he was assigned to lead a battalion. Goggin and the 32nd Virginia Infantry served under Maj. Gen. John B. Magruder in 1861 and into 1862 during the Peninsula Campaign. Goggin joined the First Corps, Army of Northern Virginia in April 1862, serving on the staff of Maj. Gen. Lafayette McLaws as his assistant adjutant general. He served in this capacity during all of the First Corps' engagements, in both the Army of Northern Virginia and the Army of Tennessee, until the spring of 1864. During the Battle of Fort Sanders in November 1863, Goggin carried a message from McLaws to Lt. Gen. James Longstreet, informing him that the attack was beginning to fail and it was futile to carry in on. When McLaws was replaced with Maj. Gen. Joseph B. Kershaw in May 1864, Goggin served as his assistant adjutant general as well. His service in this post was highly praised by Goggin's superiors.

 Passage 3:Lake Minchin was a saltwater lake, which covered the basins of the Salar de Uyuni, Salar de Coipasa, Lake Poopo and Salar de Empexa, including the towns of Llica, Oruro and the Desaguadero River valley. The lake had an extension of in east-west direction and of in north-south direction. A sill at Ulloma separated Lake Minchin from Lake Titicaca. Water levels reached an altitude of above sea level, indicating a depth of above the Uyuni basin. In the Poopo basin, water levels may have reached . At Cerro Lipillipi terraces between are dated between 25,700 and 31,750 BP. Another estimate is . Earlier estimates of the altitude are , resulting in depths of . Such water heights exceed these of preceding lakes, and together with even higher water levels of the subsequent Lake Tauca they are part of a trend of increasing water levels in the southern Altiplano which contrasts with progressively decreasing lake levels in the northern Altiplano. Earlier research suggested an opposite trend of lowering water levels in both basins. The surface area of Lake Minchin may have been , or . A lake terrace at is also attributed to Lake Minchin. The highest lake terraces at and were later found to belong to Lake Tauca, making it the deeper of the two lakes. If Minchin reached a water level of it may have spilled into the Pilcomayo River, draining from there via the Rio de la Plata into the Atlantic Ocean. It is also possible that the lake temporarily drained into the Pacific Ocean through its southwesternmost sector at Salar de Ascotán; such an outlet would have existed for only a brief time, however, before it was obstructed by volcanism. San Agustin, San Cristobal and Colcha formed islands in the lake, which was separated into a Coipasa half and an Uyuni half by a peninsula of the Serranía Intersalar; straits at Llica and Salinas de Garci Mendoza connected the two halves. Bays developed close to Isluga, Empexa and Ollagüe.
