By the fall of 1946, with WWII in the past, a new era of exuberance and growth was taking hold. Football returned with cheerful fans. Southeastern gained full accreditation and acceptance into the Southern Association of Colleges and Schools. More surrounding land was purchased for the campus, bringing the total to 375 acres. And returning GIs flooded back to Southeastern, with students from further afield also enrolling in greater numbers for the first time, leading to skyrocketing attendance.
As a result, a second wave of extensive campus construction began. āGā buildings and two steel navy barracks were also contributed by the federal government as a temporary fix for the post-war boom.
