Five significant attacks on Newfoundland took place in 1942. On 3 March 1942, launched three torpedoes at St. John's; one hit Fort Amherst and two more hit the cliffs of Signal Hill below Cabot Tower. In autumn German U-boats attacked four iron ore carriers serving the DOSCO iron mine at Wabana on Bell Island in Newfoundland's Conception Bay. The ships SS "Saganaga" and SS "Lord Strathcona" were sunk by on 5 September 1942, while SS "Rosecastle" and "P.L.M 27" were sunk by on 2 November with the loss of 69 lives. After the sinkings the submarine fired a torpedo that missed its target, the 3,000-ton collier "Anna T", and struck the DOSCO loading pier and exploded. On 14 October 1942, the Newfoundland Railway ferry was torpedoed by and sunk in the Cabot Strait south of Port aux Basques. "Caribou" was carrying 45 crew and 206 civilian and military passengers. One hundred thirty-seven lost their lives, many of them Newfoundlanders.
