Question: How many volunteers did the regiment Pierson helped organize have? Passage 1:Edward J. DeBartolo Corporation formed a joint venture with Homart Development Company, a shopping mall development subsidiary of the department store chain Sears, to begin development on Castleton Square in 1971. DeBartolo announced the mall's development in January of that year and began groundbreaking soon afterward. The original plans called for a Y-shaped enclosed mall with three anchor stores: Sears, J. C. Penney, and Rike Kumler Co. (Rike's), a department store chain based out of Dayton, Ohio. The mall would be situated on 82nd Street just outside the Interstate 465 beltway within the Castleton neighborhood on the northeastern side of Indianapolis. It was the second of three malls built by DeBartolo as a part of its expansion into Indianapolis, following Lafayette Square Mall in 1968 and preceding Washington Square Mall in 1974. The company chose to build on the northeastern side of the Indianapolis metropolitan area, as the area was projected for further suburban growth in the intervening years. Similarly, research conducted by Sears showed a trend in residential growth to the city's northeast side, thus creating a market which the chain deemed suitable for a new store. To accommodate for mall traffic, the Indiana Department of Transportation expanded 82nd Street to a four-lane divided highway. Federated Department Stores (now Macy's, Inc.), then-owners of the Rike's chain, confirmed that the third anchor of Castleton Square would instead be Lazarus, a Columbus, Ohio-based chain then also under their ownership. Also confirmed as tenants for the mall by 1972 were a Kroger supermarket, an F. W. Woolworth Company dime store, and a three-screen movie theater. Inline tenants would include Robert Hall Clothes, Hickory Farms, Kinney Shoes, Zales Jewelers, Waldenbooks, and Orange Julius.
 Passage 2:Pavle Bakić had a timar, as did his father, and held great estates around Venčac in Šumadija called "Bakić's land". He was highly viewed of by the Ottoman Empire, and had the rights to collect taxes (kharaj) from his people. In talks with Pál Tomori and Louis II of Hungary, he left his land with his family, five brothers (including Petar Bakić), and a great number of Serbs, into Hungary, and in return he received the town of Lak among other estates. With his forces he participated in the Battle of Mohács in 1526. When the succession war between Ferdinand I and John Zápolya started, he took the side of Zápolya. After the defeat of Zápolya in the Battle of Tokaj in 1527, he sided with Ferdinand and would stay faithful to him for the rest of his life. In 1528, Ferdinand confirmed Bakić and his brothers' holdings and appointed him the captain of the Serbian infantry, cavalry and river forces. In the defence of Vienna in 1529, Bakić was an important aspect with his cavalry. In charters of 1534, Ferdinand again confirmed Bakić and his brothers' holdings (Lak, Győr, Szombathely, Hédervár and all estates that were part of these towns). The fortress of Győr was administered by his Hungarian ally Count György Cseszneky. A charter dated September 20, 1537, titles him as Despot and called all Serbs to join Bakić as the Serbian Despot. Attempts made by King Ferdinand to push the Ottomans out of Slavonia, with the use of Pavle, were not successful. Bakić did not manage to liberate Osijek from the Ottomans, he then retreated to Đakovo, where he at Gorjani, in a battle against the Ottomans, died (1537). Mehmed-paša sent his son with the head of Bakić to Istanbul.
 Passage 3:In 1857, he enlisted as a private in Company K of the 7th Regiment of the New York National Guard, and was attached to the staff of Brig. Gen. William Hall. At the start of the American Civil War, Pierson helped organize the 1st New York Volunteer Infantry Regiment, and was appointed captain in May 1861. He was promoted several times and assumed command of the regiment on October 9, 1862, with the rank of colonel. Attached to the 3rd Corps, Army of the Potomac, he led the 1st New York in actions at the Seven Days Battles, Second Manassas and the Battle of Fredericksburg. After the Battle of Chancellorsville in May 1863, Colonel Pierson was honorably discharged and mustered out on May 25, 1863. For distinguished service, he was brevetted brigadier general of the United States Volunteers for "gallant and meritorious services."
