 One of the Confederate fortifications, named Fort Wade, was silenced, but the other, named Fort Cobun, continued fighting.Due to the strong Confederate resistance, Grant and Porter decided it was not feasible to make an amphibious landing at Grand Gulf, but later landed at Bruinsburg, Mississippi instead.After the Confederates were defeated at the Battle of Port Gibson on May 1, Grand Gulf was rendered indefensible and the fortifications 
were abandoned.
