In February 1948, Van Fleet was promoted to lieutenant general and sent to Greece as the head of the Joint U.S. Military Advisory Group and executor of the "Truman Doctrine". He was instrumental in the outcome of the Greek Civil War by providing advice to the Greek government and 250 military advisers, as well as administering $400 million in military aid. The central square in the northern Greek city of Kastoria has featured a bust of Van Fleet for many years, and was replaced with a new statue as recently as 2007.
