ships, Arniston had to rely instead on older, less accurate navigation methods. Navigation via dead reckoning proved particularly difficult as there were strong ocean currents combined with inclement weather that prevented a fix being obtained for several days via celestial navigation. On 29 May, land was sighted to the north at 7 am, and given the dead reckoning estimates, was presumed to be the Cape of Good Hope. The ship sailed west until 4:30 pm on 29 May, then turned north to run for St Helena. However the land sighted had in fact been Cape Agulhas (then known as "Cape L'Agullas") and the ship had also not made good headway against the current since this sighting. Compounding these navigational errors, the master had not taken any depth soundings (which would have confirmed his location over the Agulhas Bank), before heading north. Consequently, instead of being west of the Cape of Good Hope as presumed, the ship was closing on the reef at Waenhuiskrans near Cape Agulhas. The anchors were unable to hold the heavy ship in the storm, so on 30 May near 4 pm, Lieutenant Brice advised Captain Simpson to ground the ship to save the lives of those aboard. Eight minutes later, at about 8 pm, the ship struck rocks half a mile offshore and heeled into the wind. The guns on the opposite side were cut away in a failed attempt to level the ship, which soon started to break up in the waves.AJ 1816, primary sources. Only six men (the ship's carpenter and five sailors of the 378 people on board survived, after reaching the shore only with great difficulty through the high surf. The following morning the sternpost was the only part of the vessel still visible. The ship and her passengers had been lost for lack of a chronometer, or as an officer from the same convoy later wrote: Aftermath The six survivors buried the bodies found on the beach, then travelled east along the beach, expecting to reach Cape Town. However, after four and a half days, they realised their error and returned to the site of the wreck. Here they subsisted off a cask of oatmeal, while trying to effect repairs to the ship's pinnace, which had been washed ashore. They were discovered six days later on 14 June by a farmer's son, who was out hunting. Among the victims were: Captain
