On 20 December 1996, NATO transitioned its operation in support of the Dayton Peace Accords in Bosnia and Herzegovina from implementation to stabilization. As a result, Operation Joint Endeavor ended and Operation Joint Guard began. NATO's Implementation Force (IFOR) was similarly replaced by a Stabilization Force (SFOR). The US Task Force Eagle, comprised at that time of 20,000 soldiers led by elements of the 1st Infantry Division, continued to be the US component of the NATO mission. On 20 June 1998, the decision was made to scale down the size of SFOR and NATO transitioned from Operation Joint Guard to Operation Joint Forge.
