Input: Consider Input: 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.

Input: Consider Input: Question: Which event that Andre participated in had a larger attendance? Passage:His on-air return finally took place at the WWF's Super-Stars & Stripes Forever USA Network special on March 17, 1991, when he came out to shake the hand of The Big Boss Man after an altercation with Mr. Perfect. The following week, at WrestleMania VII, he came to the aid of the Boss Man in his match against Mr. Perfect. Roussimoff finally returned to action on April 26, 1991, in a six-man tag-team matchup when he teamed with the Rockers in a winning effort against Mr. Fuji and the Orient Express at a house show in Belfast, Northern Ireland. On May 10 he participated in a 17-man battle-royal at a house show in Detroit. (won by Kerry Von Erich) Making it his last WWF match. His last major WWF storyline following WrestleMania VII had the major heel managers (Bobby Heenan, Sensational Sherri, Slick, and Mr. Fuji) trying to recruit Roussimoff one-by-one, only to be turned down in various humiliating ways (e.g. Heenan had his hand crushed, Sherri received a spanking, Slick got locked in the trunk of the car he was offering to Roussimoff and Mr. Fuji got a pie in his face). Finally, Jimmy Hart appeared live on WWF Superstars to announce that he had successfully signed Roussimoff to tag-team with Earthquake. However, when asked to confirm this by Gene Okerlund, Roussimoff denied the claims. This led to Earthquake's attacking Roussimoff from behind (injuring his knee). Jimmy Hart would later get revenge for the humiliation by secretly signing Tugboat and forming the Natural Disasters. This led to Roussimoff's final major WWF appearance at SummerSlam '91, where he seconded the Bushwhackers in their match against the Disasters. Roussimoff was on crutches at ringside, and after the Disasters won the match, they set out to attack him, but the Legion of Doom made their way to ringside and got in between them and the Giant, who was preparing to defend himself with one of his crutches. The Disasters left the ringside area as they were outnumbered by the Legion of Doom, the Bushwhackers and Roussimoff, who struck both Earthquake and Typhoon (the former Tugboat) with the crutch as they left. His final WWF appearance came at a house show in Paris, France, on October 9. He was in Davey Boy Smith's corner as the Bulldog faced Earthquake. Davey Boy hit Earthquake with Roussimoff's crutch, allowing Smith to win.
