The RMS Mesaba was a steamer. She sent a very critical ice warning to the RMS Titanic, at 9:40 pm, April 14th 1912. It warned of heavy pack ice and 3 large icebergs directly in front of the ship, about 55 miles off. Sadly, it was never delivered to the bridge. She may have tried to come to the Titanic's aid but it is unknown.
