full_context: Document 1: Supreme Commander of the Swedish Armed Forces: The Supreme Commander is, apart from the honorary ranks held by the King of Sweden and in the past other members of the Swedish Royal Family, by unwritten convention normally the only professional military officer on active duty to hold the highest rank (a four-star General or Admiral). An exception was made 2009-2014 when Håkan Syrén was chairman of the European Union Military Committee.
Document 2: Mary Ball: Mary Ball was born in 1812, the second daughter of Bob Stawell Ball and his wife Mary "née" Green. She was born near Cobh, County Cork, but shortly moved with the family to nearby Youghal, County Cork. Mary had three siblings who lived into adulthood: Robert, Bent (1806-1860), and Anne, a well-known algologist. The family was Protestant and "involved in trade".
Document 3: Commander-in-chief: President Donald Trump is the current Commander in Chief of the Armed Forces of the United States. According to Article II, Section 2, Clause I of the Constitution, the President of the United States is ``Commander in Chief of the Army and Navy of the United States, and of the Militia of the several States, when called into the actual Service of the United States. ''Since the National Security Act of 1947, this has been understood to mean all United States Armed Forces. U.S. ranks have their roots in British military traditions, with the President possessing ultimate authority, but no rank, maintaining a civilian status. The exact degree of authority that the Constitution grants to the President as Commander in Chief has been the subject of much debate throughout history, with Congress at various times granting the President wide authority and at others attempting to restrict that authority.
Document 4: John Kerry: John Forbes Kerry was born on December 11, 1943 in Aurora, Colorado, at Fitzsimons Army Hospital. He was the second oldest of four children born to Richard John Kerry, a Foreign Service officer and lawyer, and Rosemary Isabel Forbes, a nurse and social activist. His father was raised Catholic (John's paternal grandparents were Austro-Hungarian Jewish immigrants who converted to Catholicism) and his mother was Episcopalian. He was raised with an elder sister named Margaret (born 1941), a younger sister named Diana (born 1947) and a younger brother named Cameron (born 1950). The children were raised in their father's faith; John Kerry served as an altar boy.
Document 5: Canadian Armed Forces: The Canadian Joint Operations Command is an operational element established in October 2012 with the merger of Canada Command, the Canadian Expeditionary Force Command and the Canadian Operational Support Command. The new command, created as a response to the cost-cutting measures in the 2012 federal budget, combines the resources, roles and responsibilities of the three former commands under a single headquarters.
Document 6: Canadian Armed Forces: The responsibility for military command remained with the British Crown-in-Council, with a commander-in-chief for North America stationed at Halifax until the final withdrawal of British Army and Royal Navy units from that city in 1906. Thereafter, the Royal Canadian Navy was formed, and, with the advent of military aviation, the Royal Canadian Air Force. These forces were organised under the Department of Militia and Defence, and split into the Permanent and Non-Permanent Active Militias—frequently shortened to simply The Militia. By 1923, the department was merged into the Department of National Defence, but land forces in Canada were not referred to as the Canadian Army until November 1940.
Document 7: Commander-in-Chief, Portsmouth: The post of Commander-in-Chief, Portsmouth was merged with that of Commander-in-Chief, Plymouth in 1969 to form the post of Commander-in-Chief, Naval Home Command. The posts of Second Sea Lord and Commander-in-Chief Naval Home Command were amalgamated in 1994 following the rationalisation of the British Armed Forces following the end of the Cold War. In 2012, however, all distinct Commander-in-Chief appointments were discontinued, with full operational command being vested instead in the First Sea Lord; he now flies his flag from HMS "Victory".
Document 8: Cyril Connolly: Cyril Connolly was born in Coventry, Warwickshire, the only child of Major Matthew William Kemble Connolly (1872–1947), an officer in the King's Own Yorkshire Light Infantry, by his Anglo-Irish wife, Muriel Maud Vernon, daughter of Colonel Edward Vernon (1838–1913) J.P., D.L., of Clontarf Castle, Co. Dublin. His parents had met while his father was serving in Ireland, and his father's next posting was to South Africa. Connolly's father was also a malacologist (the scientific study of the Mollusca, i.e. snails, clams, octopus, etc.) and mineral collector of some reputation and collected many samples in Africa. Cyril Connolly's childhood days were spent with his father in South Africa, with his mother's family at Clontarf Castle, and with his paternal grandmother in Bath, Somerset, and other parts of England.

Document 10: Ministry of Supply: The Ministry of Supply was abolished in late 1959 and its responsibilities passed to the Ministry of Aviation, the War Office and the Air Ministry. The latter two ministries were subsequently merged with the Admiralty to form the Ministry of Defence.
Document 11: Edmund Burke: Burke was born in Dublin, Ireland. His mother Mary née Nagle (c. 1702 – 1770) was a Roman Catholic who hailed from a déclassé County Cork family (and a cousin of Nano Nagle), whereas his father, a successful solicitor, Richard (died 1761), was a member of the Church of Ireland; it remains unclear whether this is the same Richard Burke who converted from Catholicism. The Burke dynasty descends from an Anglo-Norman knight surnamed de Burgh (latinised as de Burgo) who arrived in Ireland in 1185 following Henry II of England's 1171 invasion of Ireland.
Document 12: Daphne du Maurier: Daphne du Maurier was born in London, the middle of three daughters of prominent actor-manager Sir Gerald du Maurier and actress Muriel Beaumont.

Her elder sister, Angela du Maurier, also became a writer, and her younger sister Jeanne was a painter.
Document 13: United States Marine Corps: After the war, the Marine Corps fell into a malaise that ended with the appointment of Archibald Henderson as its fifth Commandant in 1820. Under his tenure, the Corps took on expeditionary duties in the Caribbean, the Gulf of Mexico, Key West, West Africa, the Falkland Islands, and Sumatra. Commandant Henderson is credited with thwarting President Jackson's attempts to combine and integrate the Marine Corps with the Army. Instead, Congress passed the Act for the Better Organization of the Marine Corps in 1834, stipulating that the Corps was part of the Department of the Navy as a sister service to the Navy. This would be the first of many times that the independent existence of the Corps was challenged.
Document 14: Dillie Keane: Born in Portsmouth in 1952, Keane is the daughter of Frank Keane, a doctor from County Mayo, by his marriage to Miriam Slattery, originally from Tralee, County Kerry, and was brought up in Portsmouth as a Roman Catholic.
