At 18.45 hours on 1 Oct 1939, U-35 attempted to stop the neutral and unarmed Suzon (Master R. Lejeune) by light signals, but she tried to escape and only stopped when a warn shot from the deck gun actually hit #2 hold. The 20 crew members then hastily abandoned ship in two lifeboats and were questioned by the Germans, who gave them the course to the nearest land. The U-boat then fired a torpedo that hit the ship on port side abreast the funnel, causing her to break in two and to sink almost immediately 42 miles 330° from Ushant. At 00.05 hours on 2 October, the survivors were picked up by HMS Acheron (H 45) (LtCdr R.W.F. Northcott, RN), escorting convoy MB-10 and landed at Brest on 4 October.
