After a series of routine rearmings near the Demilitarized Zone (DMZ), rough weather and high seas frustrated several attempts by the destroyer to come alongside. Since the destroyer's magazines were low, the need to replenish her stocks was urgent; so "Wrangell" and "George K. MacKenzie" anchored inside the sheltered lee of Cam Ranh Bay to effect the transfer. While nearby patrol craft periodically dropped antiswimmer charges and kept a lookout for possible Viet Cong interference in the operation, the job was completed in two hours. As the ship's history for the year stated: "For "Wrangell", the Camranh Bay episode was the closest she had ever brought her thousands of tons of ammunition to hostile fire. All hands breathed a sigh of relief when the exciting, risky rearming of the "MacKenzie" was over."
