The Iranians suffered tremendous casualties clearing minefields and breaching Iraqi anti-tank mines surrounding Basra, which Iraqi engineers were unable to replace. Iraq deployed its navy as a diversion and destroyed Iranian patrol craft in the Iranian port of Khor-Musa. The Iraqi Air Force was also effectively deployed, with fixed wing fighters massing fires on Iranian formations in the southern sector. After this battle, the vicious cycle of Iranian human wave assaults continued but not to the level of Operation Before the Dawn, or of the previous massive Iranian assaults of 1982.
