Task: Question Generation
Input (English): Passage: Kettle Hill was a smaller part of the San Juan Heights with San Juan Hill 20°01′12″N 75°47′54″W﻿ / ﻿20.0200185°N 75.7982129°W﻿ / 20.0200185; -75.7982129﻿  and its main blockhouses being the highest point with a dip or draw in between the two hills on a north-south axis. The heights are located about a mile east of Santiago. Elements of Conley's 10th Cavalry  took Kettle Hill on the American right with assistance from Col. Theodore Roosevelt's 1st Volunteer Cavalry  and the entire 3rd Cavalry . Most of the 10th supported by elements of the 24th and 25th colored infantry on the left took San Juan Hill. The 10th had held the center position between the two hills and when they went forward they split toward the tops of the two hills. Lieutenant Ord started the regulars forward on the American left and Roosevelt claimed he started the charge on the right. Retreating Spanish troops withdrew toward San Juan Hill still being contested. The regulars fired toward them and supported their comrades fighting on the adjacent hill. A legend was started that the Rough Riders alone took Kettle Hill, but this is not true. Sergeant George Berry  took his unit colors and that of the 3rd Cavalry to the top of Kettle Hill before the Rough Rider's flag arrived. This is supported in the writings of Pershing, who fought with Sergeant Conley and the 10th on Kettle Hill. and later led the American Expeditionary Force during the First World War.
Output (English): How many other Cavalry units assisted Conley's unit in the taking of Kettle Hill?
