The U.S. Navy attack cargo ship USS "Arneb" (AKA-56) in Antarctica during "Deep Freeze '57". "Arneb" had been damaged due to the ice pressure on 31 December 1956. On 3 January 1957, the ice pack had loosened and enabled the ice breaker USS "Northwind" (AGB-5) to lead the battered "Arneb" into port. After unloading the cargo, the crew repaired the cracks and split seams by listing the ship alternately to port and to starboard. Although having suffered a bent rudder post and a broken propeller blade, "Arneb" was able to continue the operation.
