Loss of USS Block Island (CVE-21)
1944: May 29: Loss of USS Block Island (CVE-21)
On May 29, 1944, German U-boat, U-549, torpedoed and sank USS Block Island (CVE-21) west-northwest of the Canary Islands. USS Barr (DE-576) was also damaged in this attack. Block Island was the only U.S. carrier lost in the Atlantic during World War II. Later that night, USS Eugene E. Elmore (DE-686) and USS Ahrens (DE-575) revenged the attack and sank the German submarine south-west of Madiera, Portugal. The only success U-549 had during her war patrols was with the two Navy warships on May 29.
