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until 1973 when the last remaining platoon who were acting as guards for the Australian Embassy in Saigon, were withdrawn in June 1973.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. These special teams were designed to train and advise local troops - ARVN units, Montagnards, territorial forces, and Mobile Strike (Mike) Forces. Dur: 25mins File: .mp3

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

On September 22nd, 1862, already almost two years into the US Civil War, President Abraham Lincoln issued the Emancipation Proclamation stating that, as of January 1st, 1863, all slaves within any State would be "thenceforward, and forever free." This proclamation freed 3.5 million men and women of African-American descent and, included in the proclamation, was the sentence that "the executive government of the United States, including the military and naval authority thereof, will recognize and maintain the freedom of such persons and will do no act or acts to repress such persons, or any of them, in any efforts they may make for their actual freedom." This meant that African-Americans could serve in the armed forces of the Union. Dur: 20mins File: .mp3

In the Spring of 334 BC, the 22-year-old Macedonian king, Alexander III (r. 336-323 BC - not yet ‘the Great’), invaded the vast Achaemenid Persian Empire with an elite but small army of some 30-40,000 veteran infantry and only 5,000 cavalry. This invasion was the culmination of almost a century of pressure for some Greek commander or other to punish Persia for its own invasion of Greece during the fifth century BC. Persia had also continued to seriously meddle in Greek affairs thereafter, affecting the end of the Peloponnesian War in 404 BC and with the King’s Peace in 386 BC. Dur: 31mins File: .mp3

Twelve years have passed since the disastrous Crusader Battle of Varna and three years since the fall of Constantinople to the Ottoman Empire in 1453. Europe is reeling under the relentless pressure of Ottoman advances: Serbia fell in 1455, and Sultan Mehmed II had now amassed his forces for an invasion of the Kingdom of Hungary. To launch this invasion, he first needs the fortress town of Belgrade... Dur: 20mins File: .mp3

The Italian invasion of British Somaliland is an often-overlooked action of the Second World War. Although small and a backwater of the British empire, the region would see several significant firsts of the Second World War. The loss of the colony in mid-1940 was the first significant loss of British colonial territory during the war. The loss alongside the few casualties suffered, caused frustration and concern in London. While the unexpected collapse of Italian East Africa less than a year later represented the first significant theaterwide defeat of the Axis powers. Dur: 20mins File: .mp3

Among the many brave acts of the Second Anglo-Afghan War (November 1878-September 1880), sixteen were awarded the Victoria Cross. Among this relatively small collection of awards, however, are several remarkable circumstances. The war saw the last Victoria Cross awarded to a civilian and the same award was the first to a clergyman (Reverend James Adams). Dur: 33mins  File: .mp3

At the turn of the nineteenth century, Italy, a newly unified upstart Great Power, was looking to expand its political and economic influence into neighboring North Africa. Just a few years earlier, France had taken effective control of the North African coast from Tunisia to Morocco, while Egypt was a British protectorate. Just two areas of North Africa were unoccupied by Western European powers: Morocco and Ottoman Libya. Dur: 22mins  File: .mp3
