The Turkish intervention in Korea was unique in its timeliness and urgency. The 5,000-man Turkish brigade arrived in October 1950 as U.S. forces, then acting as part of a United Nations coalition, were struggling to survive a powerful Communist Chinese offensive. The following month, the brigade managed to halt an onslaught of six Chinese divisions around Kunu-ri. After the brigade helped stabilize the front, the Commander of the UN Coalition Forces, General Douglas MacArthur, said, "the Turks are the hero of heroes. There is no impossibility for the Turkish Brigade."
As the war went on, Turkish soldiers continued to bravely aid UN forces, earning recognition from General Walton H. Walker, commander of the U.S. 8th Army, and President Harry Truman, who awarded the Turkish brigade a Presidential Unit Citation. The prestigious award, given to units of the U.S. Armed Forces and allied countries for extraordinary heroism against an armed enemy, recognized the Turkish brigade's efforts to save the U.S. 2nd Division from total annihilation, losing 717 men in the process.
Turkey ultimately became the fourth largest military contributor to the UN effort, with a total of 15,000 Turkish troops serving in Korea at various times during the war. The camaraderie on the battlefield led to deep relations between American and Turkish soldiers. After they arrived in Korea, the Turkish troops were trained and equipped by the U.S. Army, giving soldiers and officers several opportunities to strengthen their personal and professional ties.
The late Congressman John P. Murtha once noted how the Turkish intervention "gave hope to a demoralized American nation." Marking the 50th anniversary of the Korean War in 2000, Murtha recalled how Turkish soldiers, after having run out of ammunition, affixed bayonets to their rifles and continued fighting in hand-to-hand combat.
Ankara's brave decision to send troops to Korea in late 1950 also proved pivotal in securing Turkey's entry into NATO the following year. When the alliance was formed in April 1949, Turkey was not invited to join. Washington was reluctant to commit to defend distant Turkey, and had also rejected Turkish proposals for a bilateral alliance or a unilateral U.S. security guarantee. NATO's western European members did not want to risk diluting American economic aid and other assistance they were receiving.
Although some Turkish leaders wanted to pursue a more neutral foreign policy following NATO's snub, Turkish policymakers continued to pursue NATO membership, believing the alliance offered Turkey the optimal western anchor. Turkey's key contribution to the Korean conflict then made it impossible for the allies to turn down Ankara's renewed membership campaign. In September 1951, Turkey, along with Greece, had received a formal invitation to join the alliance.
Turkey has since made major contributions to NATO. During the Cold War, Turkey helped constrain the Soviet Navy in the Mediterranean, provided one of the largest armies in Europe and hosted key NATO military facilities. More recently, Turkish soldiers have contributed to NATO-backed missions in the former Yugoslavia and Libya.
