Ahoy Captain Bob
You are right that Scott sailed in the Discovery, all be it the RRS Discovery (Royal Research Ship) but in fact Scott led two expeditions.
His first expedition, in the ship Discovery, took place between 1901–04 and was half funded by the Government. Discovery was specially built for the voyage, as a research ship to go through icy seas.
In 1910, he sailed on another scientific voyage, this time in the Terra Nova, originally a whaler. Not Government funded this time so Scott had to raise funds himself, At the time it was noted that children were very happy to donate for the dogs and ponies.
The end of the Terra Nova.
In 1942 she was chartered to carry supplies for US bases in Greenland. On Sunday 12 September that year, while on a passage from Greenland to Newfoundland, she developed a bad leak and at 19.20 hours transmitted an SOS message. This was answered by the US Coast Guard Cutter Atak, which, by daybreak next day, had picked up the crew of 24 men from the burning Terra Nova, by now in a sinking condition.
The Master of the Terra Nova was the last man to board the Atak, which then finished her off with 23 rounds of 3-inch gun fire. Her approximate last position was 60°30’N 46°30’W, off the Southwestern coast of Greenland.
Its a shame that such a famous ship should have such a sad end.
