Of the Battle of Valmy, military historian J.F.C Fuller, wrote, "The Cannonade of Valmy was more than a military event; it drew a line between the form war had taken since 1648 and the form it was to assume after 1792." The events leading up to the Battle of Valmy are a good representation of such changes in political and military situations in both Revolutionary France, and the rest of Europe at that time.

True cavalry with men mounted on horse back started to appear from the 9th century BC, as chariots were slowly replaced. Imposing they were used in shock charges, their rapid movement made them ideal for reconnoissance, screening an army and for chasing down the enemy. Though despite there usefulness they only remained a small part of a Mediterranean army, comprising of perhaps only some 10% of the total numbers. In the late Roman empire period cavalry drawn from Northern Europe became more prevalent.

The expense of the horse and equipment often made it the province of aristocrats, creating at times divisions in social and political status between that of the infantry and cavalry.

In this episode Jasper, Josho, Murray, Lindsay and Michael consider questions of the tactical roll of the cavalry, the logistics of providing for the cavalry and their weapons and equipment, and the social status of the cavalry and use of "Barbarians".

Mata Hari is one of the "best known" spies of World War One. While she may not have been a "saint" by any stretch of the imagination - it is said that she "drew every man's lustful admiration and every woman's envy" - there's plenty of speculation as to whether she was really guilty of the espionage for which she was accused and for which she paid the ultimate price...execution by firing squad on 15th October 1917.

The military performance of an army is not just dependant on numbers:- the men need to be fed, equipped, quartered, transported (the list goes on). If you can deprive your opponent of these elements you can degrade his fighting ability. The policy of Scorched Earth denies your opponent of anything useful in the area they are passing through (either in attack or retreat), this can include burning of crops, ripping up rail lines or destroying buildings anything of any use is destroyed.

The Dacians lived in modern day Romania, they had long been a threat along the borders of the Roman Empire. In 101AD Trajan launched the first of two campaigns against Dacia, eventually it would become a Roman province. Though poorly documented the conflict is celebrated on Trajans column in the centre of Rome, providing a spiralling view of the campaign, and at Adamclisi (in modern day Romania) which depicts brutal fighting between Roman Legionaries and Dacian warriors.

Jasper, Josho, Michael and Lindsay discuss how these actions fit in with other actions along Romans frontiers, a look at arms and armour, the lack of sources when looking at the campaign and we take a look at Trajan himself.

In 53 B.C. a Roman army confronted a force one quarter its strength yet suffered Rome's bloodiest defeat in more than a hundred years. The Battle of Carrhae pitted 40,000 Roman soldiers against an army of a mere 10,000 of the Parthian Empire on the sands of Mesopotamia. The humiliating loss rippled through Rome and crumbled the fragile foundation of the Republic; from this rubble rose the Roman Empire. And the disaster of Carrhae, and the folly leading to it, would write a bloody epitaph of the Roman commander, Marcus Licinius Crassus. Dur: 32mins File: .mp3
