By 11:15 the advance had bogged to a virtual standstill in the face of an especially knotty core of opposition near the water's edge. The rugged terrain around the strong-point forbade effective use of supporting tanks, and the armored amphibians, because of the shore's configuration, could not hit the area. To relieve the deadlock, Lieutenant Colonel Hays ordered his battalion to pivot on the left and wheel in an arc to the beach. This maneuver, striking the enemy at right angles to the original direction of advance, was successful. Within 15 minutes a pocket of 20 to 25 well-concealed riflemen had been reduced.
