 Hugh Elton notes that Aetius and his army were one of the most effective Roman armies to have existed, with its speed and mobility pointing to a highly efficient logistical and manpower resupply system not directly evidenced by the sources.It is generally seen that the rapid fragmentation and collapse of the West after his death was a testament to his ability to hold the empire together.Aetius' legacy has been filled with controversy somewhat similar to that of Stilicho as both left the Empire significantly weaker when they died.
