Question: How long before Fort Mercer built was the city it was built to protect established? Passage:Fort Mercer was a fort on the Delaware River in New Jersey constructed by the Continental Army during the American Revolutionary War. Built by Polish engineer Thaddeus Kosciuszko under the command of George Washington, Fort Mercer was built in 1777 to block the approach to Philadelphia, Pennsylvania in concert with Fort Mifflin on the Pennsylvania side. Fort Mercer was located in an area called Red Bank, in what is now the borough of National Park, Gloucester County, New Jersey. The fort was named in honor of Brigadier General Hugh Mercer who had died earlier that year at the Battle of Princeton. The fort's site is now part of Red Bank Battlefield Historical Park, which includes a monument and museum. Several cannons attributed to British warships lost supporting the attack on the fort, and others found buried at the fort itself, are in the park.

Question: When was the field where "Refrigerator" Perry was used as a running back built? Passage:Mike Ditka, a tight end for the Bears from 1961 to 1966, was hired to coach the team by George Halas in 1982. His gritty personality earned him the nickname "Iron Mike". The team reached the NFC Championship game in 1984. In the 1985 season the fire in the BearsPackers rivalry was re-lit when Ditka used 315 pound defensive tackle "Refrigerator" Perry as a running back in a touchdown play at Lambeau Field, against the Packers. The Bears won their ninth NFL Championship, first since the AFL-NFL merger, in Super Bowl XX after the 1985 season in which they dominated the NFL with their then-revolutionary 46 defense and a cast of characters that recorded the novelty rap song "The Super Bowl Shuffle". The season was notable in that the Bears had only one loss, the "unlucky 13th" game of the season, a Monday night affair in which they were defeated by the Miami Dolphins. At the time, much was made of the fact that the Dolphins were the only franchise in history to have had an undefeated season and post-season. The Dolphins came close to setting up a rematch in the Super Bowl, but lost to the New England Patriots in the AFC title game. "The Super Bowl Shuffle" was videotaped the day after that Monday night loss in Miami.
