The cavalry 'wings' that probed ahead of the Roman Army played a key role in its campaigns of conquest, masking its marching flanks and seeking to encircle enemies in battle. However, at the very beginning of Rome’s history, it didn’t even have a cavalry, and relied on Greek-style phalanx formations instead. It began as a small cavalry arm provided by the citizen nobility, but this had proved inadequate before the end of the Republic, and Julius Caesar's cavalry was largely made up of hired allies. During the Early Principate, the armies under Augustus continued in this vein, incorporating large numbers of non-citizen auxiliary cavalry units. The provinces came under increasing attack throughout and following the chaotic mid-3rd century, and Rome took lessons from its 'barbarian' enemies in how to improve its military mobility, adopting both new, heavily armored shock cavalry and horse-archers, and vitally shaping the tactics employed during the Dominate.

Today’s guest is Mike Bishop, author of “Roman Cavalry Tactics.” We discuss how the cavalry grew to become the dominant force in Roman field armies by the twilight of the Western Empire. Eight newly commissioned artwork plates and a rich selection of artefact photographs and archaeological sources provide vivid detail and insight, helping to bring to the life the evolving tactics, clothing and weaponry of Rome's cavalry from the 2nd century BC through to the 5th century AD.
