The KPA defenders were outnumbered by more than six to one by the UN troops. KPA casualties included over 200 killed and 136 captured, primarily from the 918th Artillery Regiment and the 226th Independent Marine Regiment. The forces on Green Beach had to wait until 19:50 for the tide to rise, allowing another group to land. During this time, extensive shelling and bombing, along with anti-tank mines placed on the only bridge, kept the small KPA force from launching a significant counterattack. The second wave came ashore at "Red Beach" and "Blue Beach".
