We also examined the revised histories issued by the US Coast Guard Historical Center and the US Naval Historical Center, both of which claimed The U-869 the sinking was a result of a depth charge attack by two US Navy vessels in 1945. The conclusion we reached was that the attack by the destroyers was most likely Reexamined, Part on the already-wrecked U-869. If our conclusion is correct, then how did the U-869 come to be on the III bottom of the Atlantic? The Loss of the German Submarine Early Theories The most effective and successful branch of the German By John Chatterton, Richie Kohler, and John Yurga Navy in World War II was the U-boat arm. Hitler feared he would lose in a direct confrontation with the Royal Navy, so the German surface fleet largely sat idle at anchor. Meanwhile, the U-boats and their all- volunteer crews were out at sea, hunting down enemy vessels. They sank the merchant vessels delivering the Allies’ much-needed materials of war, and even were able to achieve some success against much larger enemy warships. -
Maritime Patrol Aviation: 90 Years of Continuing Innovation
J. F. KEANE AND C. A. EASTERLING Maritime Patrol Aviation: 90 Years of Continuing Innovation John F. Keane and CAPT C. Alan Easterling, USN Since its beginnings in 1912, maritime patrol aviation has recognized the importance of long-range, persistent, and armed intelligence, surveillance, and reconnaissance in sup- port of operations afl oat and ashore. Throughout its history, it has demonstrated the fl ex- ibility to respond to changing threats, environments, and missions. The need for increased range and payload to counter submarine and surface threats would dictate aircraft opera- tional requirements as early as 1917. As maritime patrol transitioned from fl ying boats to land-based aircraft, both its mission set and areas of operation expanded, requiring further developments to accommodate advanced sensor and weapons systems. Tomorrow’s squad- rons will possess capabilities far beyond the imaginations of the early pioneers, but the mis- sion will remain essentially the same—to quench the battle force commander’s increasing demand for over-the-horizon situational awareness.

BRIEF HISTORY of HMCS AMHERST the “Flower” Class
BRIEF HISTORY OF HMCS AMHERST The “Flower” Class corvette, HMCS AMHERST, pennant number K-148, was the first of three ships of the same class completed by the Saint John Drydock and Shipbuilding Co. Ltd.1 Laid down on 25 May 1940, she was launched on 4 December the same year, Mrs. Frederick F. Mathers, wife of the Lieutenant-Governor of Nova Scotia, sponsoring the ship.2 HMCS AMHERST may be justly called a “fighting ship.” Built quickly in a time of emergency, when ships were scare and the need great, she lived fully in a time of war and, with the coming of peace, vanished. Her’s was a lifetime of fire and peril when, it can be quite truthfully said, she did not know for months on end when the torpedoes which ended the lives of the merchant ships she shepherded and sometimes those of her mates, would come out of the dark night and destroy her too. Endurance trials for the corvette were held in July 1941 and acceptance trials on the 4th of the following month. On 5 August 1941, HMCS AMHERST was commissioned with Lieutenant-Commander A. K. Young, RCNR, as her first Commanding Officer.3 The ship was named after Amherst, the shire town of Cumberland County, Nova Scotia. Earlier, this town had been called Les Planches by the French, but was given its present name in 1759 in honour of General Amherst, Commander-in-Chief of the forces in North America and, a year later, Governor-General of British North America. Even before she was commissioned, AMHERST became a special charge of the War Workers of the Toronto Evening Telegram. -
