Some context: Abner Doubleday (June 26, 1819 - January 26, 1893) was a career United States Army officer and Union general in the American Civil War. He fired the first shot in defense of Fort Sumter, the opening battle of the war, and had a pivotal role in the early fighting at the Battle of Gettysburg. Gettysburg was his finest hour, but his relief by Maj. Gen. George G. Meade caused lasting enmity between the two men.
At the start of the Battle of Gettysburg, July 1, 1863, Doubleday's division was the second infantry division on the field to reinforce the cavalry division of Brigadier General John Buford. When his corps commander, Major General John F. Reynolds, was killed very early in the fighting, Doubleday found himself in command of the corps at 10:50 am. His men fought well in the morning, putting up a stout resistance, but as overwhelming Confederate forces massed against them, their line eventually broke and they retreated back through the town of Gettysburg to the relative safety of Cemetery Hill south of town. It was Doubleday's finest performance during the war, five hours leading 9,500 men against ten Confederate brigades that numbered more than 16,000. Seven of those brigades sustained casualties that ranged from 35 to 50 percent, indicating the ferocity of the Union defense. On Cemetery Hill, however, the I Corps could muster only a third of its men as effective for duty, and the corps was essentially destroyed as a combat force for the rest of the battle; it would be decommissioned in March 1864, its surviving units consolidated into other corps. On July 2, 1863, Army of the Potomac commander Maj. Gen. George G. Meade replaced Doubleday with Major General John Newton, a more junior officer from another corps. The ostensible reason was a false report by XI Corps commander Major General Oliver O. Howard that Doubleday's corps broke first, causing the entire Union line to collapse, but Meade also had a long history of disdain for Doubleday's combat effectiveness, dating back to South Mountain. Doubleday was humiliated by this snub and held a lasting grudge against Meade, but he returned to division command and fought well for the remainder of the battle. He was wounded in the neck on the second day of Gettysburg and received a brevet promotion to colonel in the regular army for his service. He formally requested reinstatement as I Corps commander, but Meade refused, and Doubleday left Gettysburg on July 7 for Washington. Doubleday's indecision as a commander in the war resulted in his uncomplimentary nickname "Forty-Eight Hours."
did he kill anyone?
A: Seven of those brigades sustained casualties

Some context: Louis Leo Holtz (born January 6, 1937) is a former American football player, coach, and analyst. He served as the head football coach at The College of William & Mary (1969-1971), North Carolina State University (1972-1975), the New York Jets (1976), the University of Arkansas (1977-1983), the University of Minnesota (1984-1985), the University of Notre Dame (1986-1996), and the University of South Carolina (1999-2004), compiling a career record of 249-132-7. Holtz's 1988 Notre Dame team went 12-0 with a victory in the Fiesta Bowl and was the consensus national champion. Holtz is the only college football coach to lead six different programs to bowl games and the only coach to guide four different programs to the final top 20 rankings.
In 1986, Holtz left Minnesota to take over the then-struggling Notre Dame Fighting Irish football program. A taskmaster and strict disciplinarian, Holtz had the names removed from the backs of the players' jerseys when he took over at Notre Dame, wanting to emphasize team effort. With the exception of select bowl games, names have not been included on Notre Dame's jerseys since. Although his 1986 squad posted an identical 5-6 mark that the 1985 edition had, five of their six losses were by a combined total of 14 points. In the season finale against the archrival USC Trojans, Notre Dame overcame a 17-point fourth-quarter deficit and pulled out a 38-37 win. In his second season, Holtz led the Fighting Irish to an appearance in the Cotton Bowl Classic, where the Irish lost to the Texas A&M Aggies, 35-10. The following year, Notre Dame won all eleven of their regular season games and defeated the third-ranked West Virginia Mountaineers, 34-21, in the Fiesta Bowl, claiming the national championship. The 1989 squad also won their first eleven games (and in the process set a school record with a 23-game winning streak) and remained in the No. 1 spot all season until losing to Miami in the season finale. A 21-6 win over Colorado in the Orange Bowl gave the Irish a second-place ranking in the final standings, as well as back-to-back 12-win seasons for the first time in school history. Holtz's 1993 Irish team ended the season with an 11-1 record and ranked second in the final AP poll. Although the Florida State Seminoles were defeated by the Irish in a battle of unbeatens during the regular season and both teams had only 1 loss at season's end (Notre Dame lost to seventeenth-ranked Boston College), FSU was then voted national champion in the final 1993 AP and Coaches Poll. Between 1988 and 1993, Holtz's teams posted an overall 64-9-1 record. He also took the Irish to bowl games for nine consecutive seasons, still a Notre Dame record. Following an investigation in 1999, the NCAA placed Notre Dame on two years probation for extra benefits provided to football players between 1993 and 1999 by Kim Dunbar, a South Bend bookkeeper involved in a $1.4 million embezzlement scheme at her employer, as well as one instance of academic fraud that occurred under Holtz's successor, Bob Davie. The NCAA found that Holtz and members of his staff learned of the violations but failed to make appropriate inquiry or to take prompt action, finding Holtz's efforts "inadequate." On September 13, 2008 Lou Holtz was invited back to the campus where a statue of the former coach was unveiled. The ceremony took place during the weekend of the Notre Dame/Michigan game, almost twenty-two years to the day after Holtz coached his first Notre Dame team against the Wolverines.
