One commander killed in this engagement invented a beech-loading rifle that had earlier been used in the Battle of Brandywine. The Patriot commanders in this battle utilized shifting positions along the base of the central topological entity in this battle, while the leading Loyalist officer's decision to put on a plaid shirt to cover his officer's colors resulted in his demise, as Patriot snipers trained their sights onto the shirt. Colonels John Sevier and William Campbell led part of the Patriot attack at this engagement, and were opposed by Major Patrick Ferguson's force of roughly 1,100 Loyalists. For 10 points, name this Patriot victory in the American Revolution in North Carolina, which followed Horatio Gates' defeat at Camden.
History

Iannis Xenakis used eight so-called "sound complexes" in a solo work for this instrument called Nomos Alpha. Six beats on the body of these instruments begin the main theme in Arvo Part's orchestration of Fratres for twelve of them. An ensemble consisting entirely of these instruments was founded in the 1970s by twelve members of the Berlin Philharmonic. The first of Villa-Lobos's Bachianas Brasileiras was composed for (*) eight of these instruments, while Jacqueline du Pre popularized Edward Elgar's concerto for it. J.S. Bach's six unaccompanied suites for this instrument were famously recorded by both Mstislav Rostropovich and Pablo Casals. For 10 points, name this instrument played by Yo-Yo Ma which joins two violins and a viola in a string quartet.
Fine Arts

Consoli et al. discussed data from recent high-precision ether-drift experiments which does not fit predictions made from CMB dipole data for the existence of this object. The GLIMPSE survey showed evidence for the existence of two galaxies in a Bautz-Morgan type I cluster located in it, the ACO3627, which was once known as the Norma supercluster. The Norma, Pavo-Indus and Virgo-Coma superclusters from a "great wall" like structure within this object which has no observed backside infall. Some studies indicate that mass estimates for it may be too high because infall in Shapely cluster was not accounted for, and the Zone of Avoidance has hindered the mapping of this object. It lies in the direction of hydra and centaurus, and is causing the Hubble flow of the Milky Way at 600 kilometers per second. FTP, identify this object that gets its name from pulling a lot of stuff towards it.
