Passage: Both Sui and Tang empires occupied the same location. In 582, Emperor Wen of the Sui dynasty sited a new region southeast of the much ruined Han Dynasty Chang'an to build his new capital, which he called Daxing (大興, “Great Prosperity”). Daxing was renamed Chang'an in year 618 when the Duke of Tang, Li Yuan, proclaimed himself the Emperor Gaozu of Tang. Chang'an during the Tang dynasty (618–907) was, along with Constantinople (Istanbul) and Baghdad, one of the largest cities in the world. It was a cosmopolitan urban center with considerable foreign populations from other parts of Asia and beyond. This new Chang'an was laid out on a north-south axis in a grid pattern, dividing the enclosure into 108 wards and featuring two large marketplaces, in the east and west respectively. Everyday, administrators of the two marketplaces would beat gong for three hundred times in the morning and evening to signify the start and stop of business. People lived in the wards were not allowed to go outside after curfew. Officials with higher-ranking had the privilege to live closer to the central avenue. Chang'an's layout influenced city planning of several other Asian capitals for many years to come. Chang'an's walled and gated wards were much larger than conventional city blocks seen in modern cities, as the smallest ward had a surface area of 68 acres and the largest ward had a surface area of . The height of the walls enclosing each ward were on average 9 to in height. The Japanese built their ancient capitals, Heijō-kyō (today's Nara) and later Heian-kyō or Kyoto, modelled after Chang'an in a more modest scale yet was never fortified. The modern Kyoto still retains some characteristics of Sui-Tang Chang'an. Similarly, the Korean Silla dynasty modeled their capital of Gyeongju after the Chinese capital. Sanggyeong, one of the five capitals of the state of Balhae, was also laid out like Chang'an.

Passage: The squadron arrived in Italy in March 1944 and flew its first combat mission from Celone Airfield on 30 March against an airfield at Imotski, Yugoslavia. It engaged primarily in the strategic bombing campaign against Germany. It attacked targets like marshalling yards, oil refineries and aircraft factories in Austria, Czechoslovakia, Germany, Greece, Romania and Yugoslavia. The squadron was awarded a Distinguished Unit Citation (DUC) for a mission against oil refineries in Ploesti, Romania on 18 May 1944. Clouds that obscured the target resulted in Fifteenth Air Force recalling the mission, but the squadron and the rest of the 463d Group did not receive the recall message and was the only unit to continue on, causing major destruction to the target. Although crippled by intense fighter attacks, they also inflicted severe damage on the opposing air defenses. On 24 May 1945, the 463d Group led the 5th Bombardment Wing in an attack against a Daimler-Benz tank factory at Berlin, Germany. The squadron made a successful attack despite three separate attacks by enemy air defenses, including attacks by German jet fighters. This action earned the squadron its second DUC.
