Question: Edwin Forrest's feud with William Charles Macready was the cause of what event that occurred on May 10, 1849, in Manhattan?
Context: Honner, born at Enniskillen, Ireland, 21 Dec. 1812, was a daughter of Eugene Macarthy, actor and manager, who died in the Dramatic College at Maybury, Surrey, 14 May 1866, aged 78.  Educated at Cork, she lost her mother at an early age, and being thrown on her own resources, with a younger brother to support, made a first appearance on the stage at a theatre in the south of Ireland.  She afterwards played in Dublin, and as the hero of juvenile tragedy attracted the notice of Edmund Kean and William Charles Macready.  Her first important character was Rosalie Somers in Thomas Morton's "Town and Country", which she played to Edmund Kean.  An engagement in Scotland followed, and she became a popular favourite.  In 1831 she was engaged by John Farrell for the Pavilion Theatre, London, where for two seasons she was the leading attraction.  In 1833 she transferred her services to the Coburg Theatre, and, on the retirement of G. B. Davidge the lessee, removed to Sadler's Wells, where Robert William Honner was the manager. Catherine Norton Sinclair (1817-1891) was an actress-manager who worked with such notable actors as Junius Brutus Booth, Edwin Booth, and Laura Keene.  Her sensational divorce from Edwin Forrest captivated the American public in the mid-1800s. Frederick Bartlett Conway (b. Clifton, 10 February 1819; d. Manchester, Massachusetts, 6 September 1874) was an actor.  He was the son of William A. Conway.  He early developed a taste for the stage.  After he had won a fair position in his profession in England, he came to the United States in August 1850.  Here he formed an association with Edwin Forrest, and played Iago to his "Othello", de Mauprat to his "Richelieu", and other companion parts.  After the death of his first wife, Mr. Conway married, in May, 1852, Sarah Crocker, a leading actress, and the two thenceforward acted together.  In 1859 they opened Pike's Opera House in Cincinnati, Ohio with a first-class company, but the engagement was not profitable, and they returned to the east.  In 1861, they visited England, and filled a short engagement at Sadler's Wells Theatre, London.  After their return they became star actors, and made an extensive and profitable tour.  Though somewhat pompous in manner, Frederick Conway was a good actor, with a fine personal appearance and a commanding delivery.  He was the father of Marianne "Minnie" Conway and Lilian Conway.  His grandsons, Minnie's sons, were actors Conway Tearle and Godfrey Tearle. Edwin Forrest (March 9, 1806 – December 12, 1872) was a prominent nineteenth-century American Shakespearean actor.

Edwin Forrest Harding (September 18, 1886June 5, 1970) commanded the 32nd Infantry Division at the beginning of World War II.  He graduated 74th among his classmates from the United States Military Academy in 1909, who included John C. H. Lee (12), Jacob L. Devers (39), George S. Patton (46), Horace H. Fuller (59), Robert L. Eichelberger (68), and William H. Simpson (101).  His first field command, the 32nd division was the first American unit, after the Battle for Guadalcanal, to engage in offensive operations in the Pacific Theater of Operations.  The 32nd was understrength, ill-trained, poorly equipped, and thrust into its first battle against seasoned Japanese units.  The unit finally logged a total of 654 days of combat during World War II, more than any other U.S. Army division.  They were among the first to enter the war and were still engaging attacking Japanese after the Armistice was declared.

He remained active in the minor leagues, mostly in western leagues, through 1906, and was briefly a player/manager for the Spokane Indians in 1906.
