USS Greer (DD–145) was a Wickes-class destroyer in the United States Navy, the first ship named for Rear Admiral James A. Greer (1833–1904). In what became known as the "Greer incident," she became the first US Navy ship to fire on a German ship, three months before the United States officially entered World War II. The incident led President Franklin D. Roosevelt to issue what became known as his "shoot-on-sight" order, with the intention of creating a casus belli in the Atlantic, provoking Germany to declare war on the US.
Greer was launched by William Cramp & Sons Ship & Engine Building Co., Philadelphia, 1 August 1918; sponsored by Miss Evelina Porter Gleaves, daughter of Rear Admiral Albert Gleaves; and commissioned 31 December 1918.
Greer's shake down took her to Azores, from which she rendezvoused with George Washington, carrying President Woodrow Wilson home from the Versailles Peace Conference, and escorted her to the United States. After exercises in coastal waters, Greer was assigned to Trepassey Bay, Newfoundland, for duties during a transatlantic flight by four Navy seaplanes, one of which, NC-4, safely completed the historic undertaking. After further training exercises and a European cruise, Greer was assigned to the Pacific Fleet, reaching San Francisco 18 November 1919.
Six months' duty with the Pacific Fleet terminated 25 March 1920, when Greer sailed to join the Asiatic Fleet. After standing by off Shanghai to protect American lives and property during riots there in May, Greer sailed to Port Arthur and Dairen on intelligence missions and returned to Cavite, Philippines, for fleet exercises. The destroyer returned to San Francisco 29 September 1921 via Guam, Midway, and Pearl Harbor. Greer decommissioned at San Diego 22 June 1922, and was placed in reserve.
Greer recommissioned 31 March 1930. Operating with the Battle Fleet, she participated in a variety of exercises along the coast from Alaska to Panama, with an occasional voyage to Hawaii. Transferred to the Scouting Fleet 1 February 1931, she cruised off Panama, Haiti, and Cuba before being attached to the Rotating Reserve from August 1933 to February 1934. Training exercises, battle practice, and plane guard duty filled Greer's peacetime routine for the next 2 years. She sailed for the East Coast and duty with the Training Squadron 3 June 1936. After conducting Naval Reserve cruises throughout that summer, Greer sailed for the Philadelphia Navy Yard 28 September and decommissioned there 13 January 1937.
As war swept across Europe, Greer recommissioned 4 October 1939 and joined Destroyer Division 61 as flagship. After patrolling the East Coast and Caribbean, Greer joined the Neutrality Patrol in February 1940. Detached from this duty 5 October, the destroyer patrolled the Caribbean that winter. She joined other American ships on operations in the North Atlantic early in 1941, out of Reykjavík, Iceland, and NS Argentia, Newfoundland. United States ships, as non-belligerents, could not attack Axis submarines; but, as the German High Command stepped up the pace of the war through the summer of 1941, Greer found herself involved in an incident which brought America's entry into the war nearer.
The Greer incident, September 1941
The "Greer incident" occurred on 4 September. The United States claimed that a German submarine (later identified as U-652) fired the first shot upon Greer, but made no contact. When news of the encounter reached the United States, public concern ran high. Initial reports reported that a British aircraft aided in repelling the attack.
In response, Germany claimed "that the attack had not been initiated by the German submarine; on the contrary, ... the submarine had been attacked with depth bombs, pursued continuously in the German blockade zone, and assailed by depth bombs until midnight." The communique implied that the US destroyer had dropped the first depth bombs. Germany accused President Roosevelt of "endeavoring with all the means at his disposal to provoke incidents for the purpose of baiting the American people into the war."
The United States Department of the Navy replied that the German claims were inaccurate and that "the initial attack in the engagement was made by the submarine on the Greer." Roosevelt made the Greer incident the principal focus of one of his famed "fireside chats", where he explained a new order he issued as commander-in-chief that escalated America nearer to outright involvement in the European war. In Roosevelt's words:
The Greer was flying the American flag. Her identity as an American ship was unmistakable. She was then and there attacked by a submarine. Germany admits that it was a German submarine. The submarine deliberately fired a torpedo at the Greer, followed by another torpedo attack. In spite of what Hitler's propaganda bureau has invented, and in spite of what any American obstructionist organisation may prefer to believe, I tell you the blunt fact that the German submarine fired first upon this American destroyer without warning, and with the deliberate design to sink her.
Declaring that Germany had been guilty of "an act of piracy," President Roosevelt announced what became known as his "shoot-on-sight" order: that Nazi submarines' "very presence in any waters which America deems vital to its defense constitutes an attack. In the waters which we deem necessary for our defense, American naval vessels and American planes will no longer wait until Axis submarines lurking under the water, or Axis raiders on the surface of the sea, strike their deadly blow—first." He concluded:
The aggression is not ours. [Our concern] is solely defense. But let this warning be clear. From now on, if German or Italian vessels of war enter the waters, the protection of which is necessary for American defense, they do so at their own peril. … The sole responsibility rests upon Germany. There will be no shooting unless Germany continues to seek it.
Senator David I. Walsh (Democrat–Massachusetts), isolationist Chair of the Senate Committee on Naval Affairs, scheduled a committee hearing to unearth the details of the incident, which prompted Admiral Harold R. Stark, Chief of Naval Operations, to issue a written report. Stark's account, made public in October 1941, confirmed that Greer dropped its charges only after the submarine fired its first torpedo at it, but revealed that Greer had gone in search of the submarine after its presence was noted by the British aircraft. Admiral Stark's report stated:
At 0840 that morning, Greer, carrying mail and passengers to Iceland, "was informed by a British plane of the presence of a submerged submarine about 10 miles [(16 km)] directly ahead. … Acting on the information from the British plane the Greer proceeded to search for the submarine and at 0920 she located the submarine directly ahead by her underwater sound equipment. The Greer proceeded then to trail the submarine and broadcast the submarine's position. This action, taken by the Greer, was in accordance with her orders, that is, to give out information but not to attack." The British plane continued in the vicinity of the submarine until 1032, but prior to her departure the plane dropped four depth charges in the vicinity of the submarine. The Greer maintained [its] contact until about 1248. During this period (three hours 28 minutes), the Greer manoeuvred so as to keep the submarine ahead. At 1240 the submarine changed course and closed the Greer. At 1245 an impulse bubble (indicating the discharge of a torpedo by the submarine) was sighted close aboard the Greer. At 1249 a torpedo track was sighted crossing the wake of the ship from starboard to port, distant about 100 yards [(100 m)] astern. At this time the Greer lost sound contact with the submarine. At 1300 the Greer started searching for the submarine and at 1512 … the Greer made underwater contact with a submarine. The Greer attacked immediately with depth charges.
Stark went on to report that the result of the encounter was undetermined, although most assumed from the German response that the sub had survived. In fact, U-652 had indeed survived and promptly headed west to participate in the devastating U-boat pack attack on convoy SC 42 in early September.
