| Chamberlain's famous "this country is at war with Germany" broadcast was delivered shortly after 11 in the morning. The torpedo from U-30 struck the Athenia at 7:38 that evening. She was slow to go down, disappearing beneath the waves, stern first, at 11 the next morning. | Chamberlain's famous "this country is at war with Germany" broadcast was delivered shortly after 11 in the morning.

| David Mearns, who has found some two dozen major wrecks for insurers and TV companies, says the Athenia's hull is visible in sonar data acquired by the Geological Survey of Ireland. It is split in the aft section where the torpedo hit, but otherwise is sitting proud of the sediment and looks to be in reasonable shape. | |
| To the untrained eye, sonar imagery can be difficult to interpret, but Mr Mearns says the dimensions of the target match exactly what would be expected of a 160m-long, 13,500-tonne passenger liner. What is more, the coordinates are very close to those sent out by the Athenia's radio officer in his distress call, and recorded in the logbooks of the vessels that came to the rescue. | To the untrained eye, sonar imagery can be difficult to interpret, but Mr Mearns says the dimensions of the target match exactly what would be expected of a 160m-long, 13,500-tonne passenger liner.

| "Can I go into a court of law and say, '100%, that's Athenia?' No. But barring a photograph I can say in my expert opinion there's a very, very high probability that that's Athenia. Everything fits," said Mr Mearns, who sets out the case in his book The Shipwreck Hunter. | "Can I go into a court of law and say, '100%, that's Athenia?'

| The relatively shallow water on Rockall Bank, an area of raised seabed a few hundred km from the Irish coastline, means it should be reasonably straightforward to send down a remotely operated vehicle to investigate the sonar contact. | The relatively shallow water on Rockall Bank, an area of raised seabed a few hundred km from the Irish coastline, means it should be reasonably straightforward to send down a remotely operated vehicle to investigate the sonar contact. |
| The marine scientist first got involved in the search for the wreck in a commission from the BBC. Producers had wanted to stage a live, underwater broadcast from the sunken remains of a famous ship. | The marine scientist first got involved in the search for the wreck in a commission from the BBC.

That's the ultimate goal, anyway," said Mr Mearns. | "It would be at such resolution that anyone could look for shipwrecks like the Athenia from their desk.

| The rescue effort by six other ships was nothing short of heroic, according to testimony. 1,306 individuals were successfully pulled off the Athenia in deteriorating seas. Most of those who died were in two lifeboats that were smashed just as they were about to be saved. | The rescue effort by six other ships was nothing short of heroic, according to testimony. 1,306 individuals were successfully pulled off the Athenia in deteriorating seas.

| "It was a shocking event," said Riverside curator Emily Malcolm. "We've got several items on display including the watch from the ship's cook. We've also got a detailed model of the Athenia. You can see all the lifeboats. It was something Donaldson had made when the ship was built," she told BBC News. | "It was a shocking event," said Riverside curator Emily Malcolm.

| Fritz Julius Lemp commanded submarines for another two years. He eventually lost his life in a confrontation in 1941 when his U-110 boat was forced to the surface after being damaged by depth charges. The British captured the submarine and took possession of its Enigma cipher machine. | Fritz Julius Lemp commanded submarines for another two years.

Goebbels has a reputation as a skilful propagandist but on this occasion he was ineffective, at least as far as international opinion was concerned." | "Fearing the impact of the affair on American opinion, the Germans promoted an absurd conspiracy theory, claiming that Winston Churchill, as First Lord of the Admiralty, had been responsible.
