[Q]: Question: Where was the division based that was able to dig in for a defense of Bastogne? Passage:The 9th Armored Division landed in Normandy late in September 1944, and first went into the line, 23 October 1944, on patrol duty in a quiet sector along the Luxembourg-German frontier. When the Germans launched their winter offensive on 16 December 1944, the 9th, with no real combat experience, suddenly found itself engaged in heavy fighting. The Division saw its severest action at St. Vith, Echternach, and Bastogne, its units fighting in widely separated areas. Its stand at Bastogne held off the Germans long enough to enable the 101st Airborne Division to dig in for a defense of the city. After a rest period in January 1945, the Division prepared to drive across the Roer River. The offensive was launched on 28 February 1945 and the 9th crossed the Roer to Rheinbach, sending patrols into Remagen. On 7 March 1945, elements of the 9th Armored found that the Ludendorff Bridge was still standing. When German demolition charges failed to bring the bridge down, they crossed it, disarming and removing the remaining charges, which could have exploded at any time. The Division exploited the bridgehead, moving south and east across the Lahn River toward Limburg, where thousands of Allied prisoners were liberated from Stalag XIIA. The Division drove on to Frankfurt and then turned to assist in the closing of the Ruhr Pocket. In April it continued east, encircling Leipzig and securing a line along the Mulde River. The Division was shifting south to Czechoslovakia when the war in Europe ended on 9 May 1945. All units of CCB/9 AIB of the 9th Armored Division were awarded the Presidential Unit Citation for their actions in taking and defending the Ludendorff Bridge during the Battle of Remagen in World War II.

[Q]: Question: How old was John Brown when Harris wrote a letter to him? Passage:Harris was born in Smithfield, Rhode Island in 1801 and at a young age moved with his parents to Dutchess County, New York where he worked on the family farm and taught school. In 1818 he moved to Ashtabula County, Ohio, but he returned to Rhode Island in 1823 and started working with his uncles William Harris and Samuel Harris in their manufacturing businesses at Valley Falls, Rhode Island and then Albion, Rhode Island. In 1831 Edward Harris started his own small mill in Woonsocket. He eventually built several other successful larger mills in Woonsocket. Harris made large donations to many public causes in Woonsocket, including new roads for the city, the land for Woonsocket High School, the site of Oak Hill Cemetery, and the Harris Institute (a library and auditorium for speakers), which became Woonsocket Harris Public Library, and the former Harris Institute building is now Woonsocket City Hall. Harris served in the Rhode Island State Senate and House of Representatives and was a strong abolitionist and temperance supporter. In the 1840s he ran for governor as the Liberty Party candidate advocating for abolitionism. In 1859 Harris wrote a letter and sent a check to John Brown after his conviction. Harris hosted Abraham Lincoln at his North End home when Lincoln spoke at the Harris Institute in 1860. Harris was married to Rachel Farnham and then after her death to Abby Metcalf and had children in both marriages. Harris died in Woonsocket in 1871. Besides the Harris Institute (Woonsocket City Hall), several of the buildings, which Harris constructed, survive, including Harris Warehouse (1855).
