Heavy fighting broke out in Dublin between the anti-Treaty IRA Dublin Brigade and the Free State troops. Much of O'Connell Street suffered heavy damage; the Gresham Hotel was burned and the Four Courts reduced to a ruin. Still, under Collins' direction, the Free State rapidly took control of the capital. By July 1922 anti-Treaty forces held much of the southern province of Munster and several other areas of the country. At the height of their success, they administered local government and policing in large regions. Collins, Richard Mulcahy, and Eoin O'Duffy decided on a series of seaborne landings into republican held areas, which re-took Munster and the west in July–August.
