Although its opening was originally delayed due to the COVID-19 public health emergency, the National Museum of the United States Army in Fort Belvoir, Virginia, houses historic Army artifacts like an M2 Bradley Infantry Fighting Vehicle from the 2003 Invasion of Iraq, General Grant's Forage Cap from the Civil War and an M4 Sherman tank from WWII. However, this Sherman is a rather special one. Its name is Cobra King and it holds the distinct honor of being the first tank to break through to the beleaguered 101st Airborne Division at Bastogne during the Battle of the Bulge.
Cobra King served with the 37th Tank Battalion, 4th Armored Division during WWII and fought through France, Luxembourg, Belgium, Germany, and into Czechoslovakia. Unlike regular Sherman tanks, Cobra King is an M4A3E2 "Jumbo" experimental variant. Classified as Assault Tanks, Jumbos were equipped with thicker armor than standard Shermans and were often re-armed with high-velocity 76mm M1 main guns (although Cobra King retained its factory short-barrel 75mm M3 gun during the Battle of the Bulge). The extra armor slowed the tanks down by 3-4 mph. Jumbos also featured duckbill-style extended end connectors fitted to the outside edges of their tracks for added weight-bearing and stability.
Cobra King's name follows the tank corps tradition of naming vehicles by the company's designation; Cobra King belonged to the 37th Tank Battalion's C Company. According to Army historian Patrick Jennings, Cobra King had been knocked out of action in France in November 1944. The tank was repaired and returned to action in Luxembourg. There, tank commander Charles Trover was killed by a sniper on December 23 as he stood in Cobra King's turret. Trover was replaced by Lt. Charles Boggess who commanded Cobra King during the Battle of the Bulge.
Along with Boggess, Cobra King was crewed by driver Pvt. Hubert Smith, assistant driver/bow gunner Pvt. Harold Hafner, loader Pvt. James Murphy and gunner Cpl. Milton Dickerman. The five men led General Patton's 3rd Army's relief of Bastogne on December 26. Driving at full speed and sweeping the road ahead with gunfire, Cobra King made a 5-mile push through intense German resistance toward Bastogne. "I used the 75 like it was a machine gun," Dickerman recalled. "Murphy was plenty busy throwing in shells. We shot 21 rounds in a few minutes and I don't know how much machine gun stuff."
Cobra King came across a team of U.S. combat engineers assaulting a pillbox. The tankers were wary of the engineers since German troops had been infiltrating U.S. lines dressed in American uniforms. Finally, one of the engineers approached Cobra King, stuck his hand out to Boggess and said, "Glad to see you." The engineers were Americans and part of Able Company, 326th Airborne Engineer Battalion, 101st Airborne Division. Together, Cobra King and the engineers destroyed the pillbox. The link-up marked the end of the German siege of Bastogne. For its relief of the city and the 101st, the 37th Tank Battalion was awarded the Presidential Unit Citation.
After six weeks in Bastogne waiting for a German counterattack, Cobra King and the 4th Armored Division rejoined the push into Germany. During this time, Cobra King became just another Sherman in the column of armor. Through February and March, the division broke through the Siegfried Line to the Kyll River and battled its way to the Rhine. On April 1, they crossed the Werra River and then crossed the Saale River 11 days later. The division continued to chase the Germans east and crossed into Pisek, Czechoslovakia in early May. After V-E Day on May 7, the division assumed occupation duties in Landshut, Germany until its inactivation the next year.
Cobra King remained in Germany while the 37th Tank Battalion was reactivated in 1951 and re-assigned to the 4th Armored Division in 1953 at Fort Hood, Texas. The 37th would later return to Europe; the division's 1958 yearbook featured a picture of Cobra King (yet unidentified) on display at McKee Barracks in Crailsheim, Germany. In 1971, the 4th was inactivated and redesignated the 1st Armored Division. In 1994, Crailsheim was closed and all the units posted there, along with Cobra King, were relocated to Vilseck. The 1st was later relocated to Bad Kreuznach, but Cobra King stayed behind.
Cobra King stood in silent vigil at Vilseck as an anonymous display tank. Jennings credits Cobra King's discovery to Army Chaplain Keith Goode, who suspected that the display tank might be the famous Cobra King. Army historians in Germany and the U.S. confirmed his suspicion after extensive research and the tank was shipped back to the states in 2009. Though the interior was damaged beyond repair by years of weather exposure, the exterior was given a full restoration at Fort Knox, Kentucky before Cobra King was put into storage at Fort Benning, Georgia. In 2017, the tank was trucked up to Fort Belvoir amidst the construction of the Army Museum. When the museum does open, Cobra King will proudly stand on display as "FIRST IN BASTOGNE".
