Another poem, "Gwaith Argoed Llwyfain", refers to another campaign against the Angles of Bernicia. It also provides remarkable insights. Here, the leader of the Angles is named as Fflamddwyn – perhaps meaning "flamebearer" or "flamboyant one." It may refer to Theodoric of Bernicia (r. ca. 584-591) whose reign coincides with Urien's. The idea that it refers to Ida, the first king of Bernicia (r. 547-559), is probably too early to correspond to Urien and Owain's dates (although there is some crossover with the earliest dates of Urien's reign).

The works of the sixth century AD Brittonic poet and bard, Taliesin, survive in a fourteenth century Welsh manuscript of the Llyuyr Taliessin, The Book of Taliesin. Taliesin is one of the most important figures in Welsh literature, one of the Five British Poets of Renown listed in the ninth century Historia Brittonum. Taliesin himself may have served at the courts of several kings and, although the book ascribed to him contains poems from others and from later ages, at least some of the poems are likely to be original. Others see the earliest poems as being from the ninth century (and so none are original). Several of the poems, however, describe reigns and battles which took place in sixth century Britain and shed light on what is usually regarded as a particularly dark age. Dur: 22mins File: .mp3

On 5 March, 1804, a group of 233 convict rebels revolted against their incarceration in the British colony of New South Wales (corresponding to modern Sydney, Australia). They were met by the local garrison, consisting of only 28-30 regulars and a few loyalist militia, at a place some 40km north-west of Sydney soon dubbed Vinegar Hill. Dur: 29mins File: .mp3

It is the dream of every ancient historian that some new discovery will solve a mystery of the past – some newly discovered fragment of a lost historian which will make everything clear. Such circumstances are very rare, but the Gothic War of Decius is one recent occasion where exactly the new discovery historians dream of took place. Dur: 24mins File: .mp3

The battle of Abritus saw the death of two emperors in battle against a foreign enemy – Gaius Messius Quintus Trajanus Decius, usually known as Trajan Decius (r. 249-251) and his son and co-emperor Quintus Herennius Etruscus Messius Decius, known as Herennius Etruscus (r. 251). They lost their lives intercepting an invasion of Goths led by their king, Cniva, as it attempted to leave the empire weighed down with plunder after an immensely successful two-year raid.

At the conclusion of the Malayan Emergency in July 1960, plans were put into place to incorporate British North Borneo and Singapore into Greater Malaysia. This idea was met with fierce opposition from President Sukarno of Indonesia and in 1962 Indonesia began supporting revolutionary factions on the large, dense jungle island of Borneo.

For the battle of Chaeronea, we get none of the detailed deployment which we get for the subsequent battles of Alexander in sources such as Arrian, Plutarch, Curtius Rufus, and even in Diodorus himself. We can use those later deployments to our advantage, however, as Macedonian deployment remained remarkably similar - and, having learned so many lessons evident at Chaeronea, why would Alexander deviate from what had happened there – especially when his subsequent battles too brought him so much success.

Australia's involvement and commitment to the Vietnam War continued until 1973 when the last remaining platoon who were acting as guards for the Australian Embassy in Saigon, were withdrawn in June 1973. As with American involvement, Australia's contribution also escalated over time. Following the arrival of the AATTV in 1962, in August 1964 the Royal Australian Airforce (RAAF) began to run supply missions to Vung Tau, the port south of Saigon. Dur: 23mins File: .mp3

Australia’s involvement in the Vietnam War began in 1962. In July that year, the Australian Army Training Team Vietnam (AATTV) (or 'the Team') first arrived, consisting of thirty military advisers.

Arthur Martin-Leake, serving as a lieutenant in the Royal Army Medical Corps in 1914 was the first man to be awarded a Bar to the Victoria Cross he received during the Second Boer War in 1902. In both circumstances Martin-Leake's conduct was to put the lives of his injured comrades first despite being exposed to constant enemy fire, and being wounded himself. Martin-Leake is the only recipient to gain his two Victoria Crosses in separate wars. Only two other men have been awarded two Victoria Crosses: Captain Noel Godfrey Chavasse in 1916 and 1917, and Captain Charles Upham in 1941 and 1942. Dur: 20mins File: .mp3
