Gwin's Army

Gwin's Army was a Super Mutant army that attacked the Minutemen in 2288.

History
A large band of Super Mutants had taken up residence in East and South Boston, and preyed upon local caravans and travelers. Their existence was threatened with the re-establishment of the Minutemen, who began a campaign to eliminate Super Mutants following their defeat of the Institute. To avoid extinction, the Super Mutants rallied behind Gwin, a Super Mutant that led a band of mutants from the Gwinnett Factory and restaurant in East Boston. Gwin's Army mobilized and tried to wipe out of the Minutemen's presence in Boston by storming the Castle.

The Minutemen General, Glenn Cunningham, received word of the attack before it began from scouting parties and quickly arrived at the Castle. Defenses were hastily added to the Castle. Gwin's Army then began its attack. The Sole Survivor and the Minutemen managed to kill two Super Mutant Behemoths in the attack, and ultimately, the attack was defeated.

Aftermath
The Super Mutants would never recover from the attack. East Boston would be secured by the Minutemen, with Gwinneth Factory and Restaurant being captured by the Minutemen. Further inroads would be made in Boston, with a combined Minuteman-Diamond City force taking Trinity Plaza and Tower from the Super Mutants, weakening their presence in Central Boston.

The attack spurred the Minutemen to quickly continue rebuilding the Castle, leading to the rebirth of The Castle as a major settlement in the Commonwealth.
