In a daring shallow water attack, a single torpedo from the U-136 tore open the starboard side of the Arundo just below the bridge and blew off the hold covers. The stricken ship heeled over to starboard and sank in only five minutes. Survivors of the attack were soon picked up by nearby vessels, but her cargo of war materiel outward bound for the campaign in North Africa never made it. That cargo included jeeps, big 10-wheeled army trucks, 2 locomotives, and 5000 cases of Canadian beer. After the war the Arundo was wire dragged and otherwise demolished, and her exact location was lost. There are several other wrecks in close proximity which have all gone under the name Arundo until the true Arundo was finally re-identified.

What remains of the real Arundo is more a vast debris field than a ship, although some parts are still tall and almost recognizable. The highest parts near the bow are at about 110 ft, but the bulk of the wreck is at 120-130 ft, and the stern goes down to 140 ft at the sand. This is not a dive for the faint-hearted. You can expect a long boat ride to cold, silty, dark conditions in the Mud Hole, and the depth of this site is going to require a considerably higher level of experience and equipment than most others, and should only be attempted by those who are realistically prepared. The Arundo is also heavily fished, and offers myriad ways for the unwary diver to get entangled in the usually poor visibility. This is a two-knife double-tank decompression dive.
