There have been two military efforts codenamed Pegasus, one in 1944 and the other in 1968.

Operation Pegasus was an Allied action in World War II as a consequence of the failure of Operation Market Garden. Some surviving soldiers from the 1st Airborne Division had avoided capture and sought shelter in the forests to the west around Ede. Operation Pegasus was the efforts to bring these soldiers across the Rhine on October 22-23 1944.

The Allies held Nijmegen and the land north between the Waal and the Rhine. The Dutch Resistance escorted the men from Ede to the bank of the Rhine west of Renkum. Just after midnight on October 23 men of the 101st Airborne Division and the Royal Engineers took assault boats across the river to gather these men, 140 men were recovered in a little over an hour, including Brigadier Gerald Lathbury . A further operation in November to rescue soldiers further east at Heteren failed with the soldiers awaiting rescue were intercepted and killed or captured.

Operation Pegasus was the relief of the besieged Marine Corps garrison at Khe Sanh during the Vietnam War. Helicopters moved of elements of the U.S. First Cavalry Division to a landing zone. There they linked up with a relief column traveling overland to the city on 7 April, 1968.
