The 6th (Inniskilling) Dragoons was a cavalry regiment in the British Army, first raised in 1689 as Sir Albert Cunningham's Regiment of Dragoons.
 One of the regiment's most notable battles was the Battle of the Boyne in July 1690.
 It became the 6th (Inniskilling) Regiment of Dragoons in 1751.
 The regiment also fought with distinction in the Charge of the Union Brigade at the Battle of Waterloo and again as part of the successful Charge of the Heavy Brigade against superior numbers at the Battle of Balaclava during the Crimean War.
 The First World War sounded the death knell for mounted cavalry as it became apparent that technology had moved forward with greater destructive power and made horsed cavalry redundant on the modern battlefield.
 The British Army reorganised and reduced its cavalry corps by disbanding or amalgamating many of its famous cavalry regiments.
 The Inniskillings was one of those affected.
 It saw service for two centuries, including the First World War, before being amalgamated with 5th (Princess Charlotte of Wales's) Dragoon Guards to form 5th/6th Dragoons in 1922.
The 6th Connecticut Regiment was raised on May 1, 1775, at New Haven, Connecticut, as a provincial regiment for the Continental Army.

 The regiment saw action at the siege of Boston, the Battle of Long Island, the New York Campaign, and its colonel and company of light infantry served in the Corps of Light Infantry at the Battle of Stony Point.

 After the armistice the regiment eventually returned to Australia in March 1919.
 For its role in the war the regiment was awarded sixteen battle honours.
 During the inter-war years, the regiment was re-raised as a part-time unit based in New South Wales, adopting the designation of the "New South Wales Mounted Rifles".
 It was later converted to a motor regiment during the early years of the Second World War before being redesignated as an armoured car regiment.
 Nevertheless, it was disbanded in early 1943 without having been deployed overseas.
 During the post war years, the regiment was re-raised as part of the Citizens Military Force, and in 1956 was converted into an infantry unit, and in 1960 was subsumed into the Royal New South Wales Regiment.

 In that role, the 2/6th saw action in the North Africa campaign and in the Middle East during 1940–41, where the regiment distinguished itself at Bardia, Tobruk and in Syria.
 Later, following Japan's entry into the war, the 6th Division was brought back to Australia and following a re-organisation, the regiment was converted into a cavalry commando regiment, incorporating the independent companies that had been formed at the start of the war.
 In late 1944, the 2/6th Cavalry Commando Regiment was deployed to New Guinea, where it participated in one of the final Australian campaigns of the war in the Aitape–Wewak area.
The Battle of the Boyne (Irish: "Cath na Bóinne" ] ) was a battle in 1690 between the forces of the deposed King James II of England, and those of Dutch Prince William of Orange who, with his wife Mary II (his cousin and James's daughter), had acceded to the Crowns of England and Scotland in 1688.
 The battle took place across the River Boyne near the town of Drogheda in the east of Ireland, and resulted in a victory for William.
 This turned the tide in James's failed attempt to regain the British crown and ultimately aided in ensuring the continued Protestant ascendancy in Ireland.
The Battle of Chunuk Bair (Turkish: Conk Bayırı Muharebesi ) was a World War I battle fought between the Ottoman defenders and troops of the British Empire.
 British units that reached the summit of Chunuk Bair early on 8 August 1915 to engage the Turks were the Wellington Battalion of the New Zealand and Australian Division, 7th Battalion, Gloucestershire Regiment and 8th Battalion, Welch Regiment of the 13th (Western) Division.

 The New Zealand troops were relieved by 8:00 pm on 9 August by the 6th Battalion, Loyal North Lancashire Regiment and 5th Battalion, Wiltshire Regiment, who were massacred and driven off the summit in the early morning of 10 August, by an Ottoman counter-attack led by Mustafa Kemal.
 The capture of Chunuk Bair, (Turkish: "Çanak Bayır" Basin Slope, now "Conk Bayırı"), the secondary peak of the Sari Bair range, was one of the two objectives of the Battle of Sari Bair, the British August Offensive at Anzac Cove and Suvla, to try to break the stalemate that the campaign had become.
 The capture of Chunuk Bair was the only success for the Allies of the campaign but it was fleeting as the position proved untenable.
 The Ottomans recaptured the peak for good a few days later.
