IN: 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."

what was their relationship like?

OUT: Meade also had a long history of disdain for Doubleday's combat effectiveness,

input: Hammill's split with the group was amicable, and Banton, Jackson, and Evans, among others, all contributed to his solo work at various times. By 1975, the members of the band were ready to work with each other again, and they decided to reform the band. All the members were keen on carrying on with new music, with no nostalgia for their previous era, and did not want to play earlier stage favourites such as "Killer" (the opening track on H to He, Who Am the Only One) and "Theme One". "We didn't want to continue as if nothing had happened," said Hammill.  The reformed band worked at a prolific pace, rehearsing, and touring France before recording three new albums in just 12 months, beginning with Godbluff (October 1975). Unlike the earlier work with John Anthony at Trident, the sessions were produced by the band themselves, and both the Melody Maker and Sounds thought they were a tighter and more cohesive unit than previously. The album in particular saw Hammill making significant use of the Hohner clavinet keyboard. Still Life followed on 15 April 1976. Banton considers this album one of his favourites by the group.  In the summer of 1975, the band gigged in Italy without incident, but when they returned to tour there in November, the intense political situation the country was going through caught up with them. The opening concert in Padova was marked with clashes with communists delivering political speeches, and the audience started throwing missiles towards the stage. After a gig without incident in Genoa, the third day of the tour at the PalaSport in Rome, in front of 40,000 people, saw similar confrontations to the Padova gig. A fire broke out at the venue, but was brought under control. The next day, the band learned that most of their gear had been stolen from the tour van, including Hammill's blue Fender Stratocaster, christened "Meurglys". Despite threats from promoters that the band would continue the tour using hired equipment (which Jackson considered impossible given the electronic modifications he had made to his saxophones), they abandoned the tour. Miraculously, all of Jackson's saxophones had survived the theft.  In December 1976, following World Record, Banton quit, quickly followed by Jackson in February 1977. Nic Potter returned to replace Banton, and in a typically eccentric move Jackson was replaced by a violinist, Graham Smith (formerly of Charisma folk-rock band String Driven Thing). This line-up produced the album The Quiet Zone/The Pleasure Dome (September 1977). The band also shortened its name to Van der Graaf. Charles Dickie then joined the band on cello, documented on the live double-album Vital, which saw a brief reunion with Jackson. By the time Vital was released, in July 1978, the band had already split, because of lack of record company support in the United States and financial difficulties.  In 1982 a collection of out-takes and rehearsal recordings from the 1972-1975 hiatus was released (initially on cassette only), called Time Vaults. These are not studio-quality recordings.
