Birth of Sir John Greer Dill, Irish-born British Army Officer

Sir John Greer Dill, senior British Army officer with service in both World War I and World War II, is born on December 25, 1881, at Lurgan, County Armagh. From May 1940 to December 1941, he is the Chief of the Imperial General Staff (CIGS), the professional head of the British Army, and subsequently serves in Washington, D.C., as Chief of the British Joint Staff Mission and then Senior British Representative on the Combined Chiefs of Staff (CCS).

Dill is the only son of John Dill, bank manager, and Jane Dill (née Greer). He is educated at Cheltenham College in England before entering the Royal Military College (RMC), Sandhurst. Commissioned as a second lieutenant, he joins the Prince of Wales’s Leinster Regiment (Royal Canadians) in May 1901 and serves in South Africa for the remainder of the Second Boer War. Promoted to captain in 1911, he is a student at the Staff College, Camberley, at the outbreak of World War I. He holds several important staff appointments during the war, including brigade major of 25th Brigade (8th Division) and General Staff Officer (Grade 2) to the Canadian Corps. Present at the battles of Neuve Chapelle, Aubers Ridge, Arras, and Third Ypres, at the end of the war he is serving as chief of operations branch at GHQ with the temporary rank of brigadier general. He is awarded the Distinguished Service Order (DSO) (1915), the Order of St. Michael and St. George (CMG) (1918), the French Legion of Honour and the Belgian Order of the Crown.

Remaining active during the interwar years, Dill serves as chief assistant to the commandant of the Staff College (1919–22) before commanding the Welsh Border Brigade, TA (1922–23), and 2nd Infantry Brigade at Aldershot (1923–26). In late 1926, he is appointed army instructor at the newly established Imperial Defence College. A period in India follows as general staff officer of the Western Command (1929–31), based at Quetta. On return to England, he is promoted to major general and made commandant of the Staff College. Appointments as commander of the British forces in Palestine and Transjordan (1936–37) and the Aldershot Command (1937–39) follow. During this period, he shows a remarkable ability to both train and inspire those under his command. Most of his colleagues expect him to become the new chief of the Imperial General Staff and are surprised when Major General Lord Gort, junior to Dill in both rank and seniority, is appointed to the post.

At the outbreak of World War II Dill commands I Corps British Expeditionary Force (BEF) in France and is made a full general. In April 1940, he is made vice-CIGS and in May takes over as CIGS. His initial period in office is not a happy one, and he has to inform the public of setbacks in both Norway and France. His workload is enormous, and after the evacuation at Dunkirk in late May he devotes himself to preparing the defences of Britain against invasion. He clashes with Winston Churchill throughout 1941, advocating a more cautious and realistic approach to the situations in North Africa, Greece, and Crete.

The workload begins to affect his health adversely, and in November 1941 it is announced that he will resign as CIGS on reaching the age of 60 and serve as governor-designate of Bombay with the rank of field marshal. He seeks to be more actively involved in the war effort, however, and in December 1941 he visits the United States with Churchill, remaining there as head of the British joint staff mission in Washington, D.C. He plays a significant role in promoting Anglo–American military cooperation and attends the Casablanca, Quebec, and Tehran conferences.

In late 1944 his health again breaks down and he dies from aplastic anemia on November 4, 1944, at the Walter Reed General Hospital, Washington, D.C. After a memorial service at Washington National Cathedral, he is buried with full military honours at Arlington National Cemetery in Arlington County, Virginia. President Franklin D. Roosevelt later pays tribute to him as a great soldier and friend, “the most important figure in the remarkable accord which has been developed in the combined operations of our two countries.”

Dill first marries (1907) Ada Maud Le Mottée, daughter of Col. William Le Mottée of the 18th Regiment. Their son, Major John de Guerin Dill, serves as an artillery officer throughout World War II. In October 1941, Dill marries Nancy Isabelle Charrington, widow of Brigadier Denis Walter Furlong. Dill’s honours include a GCB (1942), an honorary degree from Princeton University (1944), the Howland Memorial Prize of Yale University (1944), and a posthumous Distinguished Service Medal (DSM) from the United States government. There are portraits of him in Cheltenham College and the Imperial War Museum, and a statue in Washington, D.C.

Death of Major General William Hickie, Irish-Born British Army Officer

Major General Sir William Bernard Hickie, KCB, Irish-born senior British Army officer and Irish nationalist politician dies in Dublin on November 3, 1950. He sees active service in the Second Boer War from 1899 to 1902, is Assistant Quartermaster General in the Irish Command from 1912 to 1914 and serves in World War I from 1914 to 1918. He commands a brigade of the British Expeditionary Force in 1914 and is commander of the 16th (Irish) Division from 1915 on the Western Front.

Hickie is born on May 21, 1865, at Slevoir, Terryglass, near Borrisokane, County Tipperary, the eldest of the eight children of Colonel James Francis Hickie and his wife Lucila Larios y Tashara, originally of Castile. He is educated at St. Mary’s College, Oscott, Birmingham, England, a renowned seminary for training youths of prosperous Roman Catholic families.

Hickie attends the Royal Military College, Sandhurst, from 1882 to 1885. He is commissioned into his father’s regiment, the Royal Fusiliers at Gibraltar, in 1885 and serves with them for thirteen years in the Mediterranean, Egypt, and India, during which time he is promoted to captain on November 18, 1892. In 1899 he graduates as captain at the Staff College, Camberley, and is selected when the Second Boer War breaks out as a Special Service Officer in which capacity he acts in various positions of authority and command. He leaves Southampton for South Africa on board the SS Canada in early February 1900, and is promoted from captain of mounted infantry to battalion command as major on March 17, 1900. He is subsequently in command of a corps until eventually at the end of 1900 he is given command of an independent column of all arms. He holds this position for eighteen months. He serves with distinction at the Battle of Bothaville in November 1900, and receives the brevet promotion to lieutenant colonel on November 29, 1900. He serves in South Africa throughout the war, which ends with the Treaty of Vereeniging in June 1902. Four months later he leaves Cape Town on the SS Salamis with other officers and men of the 2nd battalion Royal Fusiliers, arriving at Southampton in late October, when the battalion is posted to Aldershot Garrison. In December 1902 he is elected a Fellow of the Royal Geographical Society (FRGS).

After the end of the war in South Africa there follows various staff appointments, the first from December 1902 as deputy-assistant adjutant general for district staff in the Cork district. In 1907 Hickie is back in regimental service in Dublin and Mullingar with the 1st Royal Fusiliers, where he is in command of the regiment for the last two years. From 1909 to 1912 is appointed to the Staff of the 8th Infantry Division in Cork where for four years he is well known in the hunting field and on the polo ground. In May 1912, he is promoted to colonel and becomes Quartermaster General of the Irish Command at Royal Hospital Kilmainham for which he is appointed a Companion of the Order of the Bath.

When war is declared, the Staff of the Irish Command becomes automatically the staff of the II Army Corps and accordingly with the outbreak of World War I in August 1914, Hickie is promoted to brigadier general and, as part of the British Expeditionary Force in France, takes charge of the Adjutant and Quartermaster-General’s Department during the retreat of the II Corps after the Battle of Mons, to Paris, and during the First Battle of the Marne. In mid-September 1914, he relieves one of the brigadiers in the fighting line as commander of the 13th Brigade (5th Infantry Division) and then commands the 53rd Brigade (18th Infantry Division) until December 1915, when he is ordered home to assume command of the 16th (Irish) Division at Blackburn.

Promoted to major general, Hickie takes over from Lieutenant General Sir Lawrence Parsons. It is politically a highly sensitive appointment which requires the professionalism and political awareness he, fortunately, possesses as the division is formed around a core of Irish National Volunteers in response to Edward Carson‘s Ulster Volunteers. He is much more diplomatic and tactful than his predecessors and speaks of the pride which his new command gives him but does not hesitate to make sweeping changes amongst the senior officers of the Irish Division. After putting the division through intensive training, it leaves under Irish command of which each man takes personal pride. It arrives in December 1915.

In the next two years and four months during which Hickie commands the 16th (Irish) Division, it earns a reputation for aggression and élan and wins many memorials and mentions for bravery in the engagements during the 1916 Battle of Guillemont and the capture of Ginchy, both of which form part of the Battle of the Somme, then during the Battle of Messines, the Third Battle of Ypres and in attacks near Bullecourt in the Battle of Cambrai offensive in November 1917.

During this period the Division makes considerable progress in developing its operational techniques but at a price in losses. The growing shortage of Irish replacement recruits, due to nationalist disenchantment with the war and the absence of conscription in Ireland, is successfully met by Hickie by integrating non-Irish soldiers into the division.

In February 1918, Hickie is invalided home on temporary sick leave, but when in the hospital the German spring offensive begins on March 21, with the result that after his division moves under the command of General Hubert Gough it is practically wiped out and ceases to exist as a division. Although promised a new command, this does not happen before the Armistice in November. He typifies the army’s better divisional commanders, is articulate, intelligent and is competent and resourceful during the BEF’s difficult period 1916–17, laying the foundations for its full tactical success in 1918. He is advanced to Knight Commander of the Order of the Bath in 1918.

Hickie retires from the army in 1922, when the six Irish line infantry regiments that have their traditional recruiting grounds in the counties of the new Irish Free State are all disbanded. He identifies himself strongly with the Home Rule Act and says that its scrapping is a disaster and is equally outspoken in condemning the activities of the Black and Tans. In 1925, he is elected as a member of Seanad Éireann, the Irish Free State Senate.

Hickie holds his seat until the Seanad is dissolved in 1936, to be replaced by Seanad Éireann in 1937. He is President of the Area Council (Southern Ireland) of the Royal British Legion from 1925 to 1948. He never marries.

Hickie dies on November 3, 1950, in Dublin and is buried in Terryglass, County Tipperary.

Birth of Patrick Hennessy, Irish Realist Painter

Patrick Anthony Hennessy RHA, Irish realist painter known for his highly finished still lifes, landscapes and trompe-l’œil paintings, is born in Cork, County Cork, on August 28, 1915. The hallmark of his style is his carefully observed realism and his highly finished surfaces, the result of a virtuoso painting technique.

Hennessy is the son of John Hennessy an army sergeant major from County Kerry and Bridget Hennessy from Cork. His father is killed in World War I at the Battle of Passchendaele in 1917. In 1921, when he is five years old, his mother remarries in Cork. Her second husband is a Scot named John Duncan and shortly afterwards the whole family moves to Arbroath, Scotland, where Duncan has relatives.

Hennessy is educated in Arbroath at St. Thomas RC Primary School followed by secondary education at Arbroath High School, where he begins to show an aptitude for art, leaving in 1933 with the Dux for Art and an accompanying medal. In the autumn of 1933 he enrolls at the Dundee of Jordanstone College of Art & Design, for a four-year Diploma course in Drawing and Painting under James McIntosh Patrick and Edward Baird. Here he meets Harry Robertson Craig who becomes his lifelong companion. He plays a full part in the social activities of the college, winning a fancy-dress award at the Christmas revels in 1935 and producing a ballet “Paradise Lost” the following year. He gains a First-Class Pass in each year of the course along with winning first prize in 1934 and 1936 for work done during the summer vacation. He graduates with a First-Class Distinction in 1937.

Having gained a scholarship, Hennessy continues his studies at the Dundee of Jordanstone College of Art & Design for a further year by doing a Post-Graduate Diploma course in Drawing and Painting. Within a month of gaining his Post-Graduate Diploma he holds his first joint exhibition at the Art Galleries in Arbroath. In June 1938 he is awarded the Annual Travelling Scholarship for further studies in Paris and Italy. In Paris he meets up with the artists Robert Colquhoun and Robert MacBryde, whom he had met the previous year, the three travelling south together to Marseilles towards the end of that year. On his return to Scotland he is selected for the residential summer school course at Hospitalfield House near Arbroath under James Cowie. Two of his paintings, a still life and a self-portrait, are accepted that year by the Royal Scottish Academy for their Annual Exhibition. However, by the autumn of 1939 with war looming and feeling somewhat disenchanted on his return to Scotland, he decides to return to Ireland.

On arrival in Dublin Hennessy is offered an exhibition in December 1939 at the Country Shop on St. Stephen’s Green which is opened by Mainie Jellett. This attracts favourable attention. During the early 1940s he lives at various addresses in and around Dublin with frequent trips to Cork. In 1940 he is invited to join the Society of Dublin Painters and holds regular annual exhibitions of his work there during the 1940s and early 1950s. These exhibitions are supplemented by an eclectic mix of commissions, mostly portraits which he undertakes during this period. In 1941 he has three of his paintings accepted by the Royal Hibernian Academy (RHA) for their annual exhibition. This is the beginning of a long relationship with the RHA. He exhibits there virtually every year from 1941 until 1979, the year before his death.

From the early 1940s onwards, Hennessey’s work sometimes incorporates a homosexual visual subtext. He re-unites with Harry Robertson Craig in 1946 and soon after they move to Crosshaven, County Cork, and later to Cobh. In 1947, Time magazine selects him as one of Ireland’s outstanding painters, in recognition of the important position he has then attained in the art world. In 1948 he has an exhibition at the Victor Waddington Gallery, Dublin, and that same year is elected an associate of the Royal Hibernian Academy and a full member the following year. In 1950 his painting De Profundis is selected for the Contemporary Irish Painting exhibition that tours North America. As a result of this tour, the American public and critics begin to take notice of his work. In 1951 he visits Italy, taking in Venice and Sicily and returning to Dublin with many of his canvases painted abroad. One of these paintings, Bronze Horses of St. Marks, is exhibited at the Royal Academy of Arts in London in 1954.

In 1956, a friend of Hennessy, David Hendriks, opens the Ritchie Hendriks Gallery on St. Stephen’s Green, Dublin and it is this gallery that is to be the main outlet for his work over the following 22 years. In October 1956 the Thomas Agnew Gallery in London holds an exhibition of his work comprising 38 of his paintings. However, during the winter of 1959 he becomes seriously ill with pneumonia. As a consequence of this, in the autumn of that year he and Craig decide to winter in Morocco. This is the beginning of a new era in both their lives. They would never again spend a full year in Ireland. His exhibitions at the Ritchie Hendriks Gallery had for many years enjoyed favourable reviews from the art critics but in the 1960s this changes with critics claiming his paintings to be dull, repetitive and suggest he needs to explore new areas. Despite the barrage of criticism, in 1965 the Guildhall Gallery in Chicago offers him a major exhibition. Shortly after this exhibition takes place in 1966, he becomes one of the artists on permanent display at the gallery with an annual exhibition. The North American market is extremely lucrative for him and by the end of the decade he is selling more of his work in the United States than in Ireland. In 1968 he finally moves to Tangier, Morocco on a permanent basis and in 1970 sells his studio on Raglan Lane, Dublin.

In Morocco, Hennessy paints prolifically for nine years to keep up with demand from the Hendriks Gallery and Guildhall Gallery along with the RHA. In 1975 the Guildhall Gallery mounts a highly successful Retrospective of his work. In 1978 he has his last exhibition in Dublin at the Hendriks Gallery. By this time he has moved to the Algarve, Portugal and is beginning to have health problems.

In November 1980, with his health deteriorating, Craig brings Hennessy to a hospital in London for treatment. However, on December 30, 1980 he dies from cancer. Following cremation his ashes are buried in nearby Golders Green Crematorium. He leaves his entire estate to Harry Robertson Craig with the proviso that on Craig’s death the Royal Hibernian Academy should be the beneficiary. This legacy has been used to set up the annual Hennessy Craig Scholarship for aspiring artists.

Hennessy falls into the category of painter who develops a distinctive personal style, labelled at various times in his life as a Traditional Realist, Romantic, Photo Realist, Illusionary and Surrealist. However, he always remains intrinsically himself. His subjects range from still life and interiors to landscapes and portraits.

Examples of Hennessy’s work can be found in the public collections of the Crawford Art Gallery, the Dublin City Gallery The Hugh Lane, the Irish Museum of Modern Art (IMMA), the Limerick City Gallery of Art (LCGA), the National Gallery of Ireland (NGI), the National Self-Portrait Collection of Ireland (NSPCI) at the University of Limerick (UL), and in the collections of University College Cork (UCC) and University College Dublin (UCD).

Birth of Sir William Bernard Hickie, British Army General

Sir William Bernard Hickie, British Army general, commander of the 16th (Irish) Division (1915–18) and an Irish nationalist politician, is born on May 21, 1865, at Slevoir, Terryglass, near Borrisokane, County Tipperary.

Hickie is the eldest son of Colonel James Francis Hickie, JP, of Slevoir, former commanding officer of the 7th Royal Fusiliers, and Lucila Calista (de Tejada) Hickie, daughter of Don Pablo Lariosy Herreros de Tejada of Laguna de Cameros, Castile. He is educated at St. Mary’s College, Oscott, before attending the Royal Military College, Sandhurst, and is commissioned into the Royal Fusiliers in 1885, serving in Egypt and India.

A major at the outbreak of the Second Boer War in 1899, Hickie serves on the staff of Lieutenant-Colonel P. W. J. Le Gallais, commanding officer of the mounted infantry. On November 6, 1900, he is involved in an attempt to capture General Christiaan De Wet at the Battle of Bothaville, when a force led by Le Gallais and Lieutenant-Colonel Wally Ross storm De Wet’s camp. De Wet escapes, while a rearguard of 100 men engages the British force. In a fierce fight Le Gallais is killed, and Wally Ross is badly wounded. Hickie decides to charge the Boer position and leads his small force forward just as reinforcements under Major-General C. E. Knox arrive. The Boers immediately surrender, and some are found with explosive bullets. He wants to execute them immediately, but Knox insists that they be tried. Exasperated with the whole affair, Hickie gives a highly critical interview after the action which is later published in The Times History of the War in South Africa (7 vols, 1900–09), edited by Leo Amery.

Hickie is promoted to brevet lieutenant colonel in 1901 and appointed deputy-assistant adjutant general of the 8th division (1903–06). In 1906, he is given command of the 1st battalion of the Royal Fusiliers. Promoted to colonel in 1912, he serves as assistant quartermaster general of the Irish command (1912–14) and is appointed a Companion of the Order of the Bath in 1914. On the outbreak of World War I, he is promoted to brigadier general and serves in Belgium and France in command of the adjutant’s and quartermaster-general’s department of II Corps. In this capacity, he is involved in the retreat following the Battle of Mons and during the First Battle of the Marne (September 1914). In December 1915, he is appointed to command the 16th (Irish) Division, with the rank of major general, replacing General Sir Lawrence W. Parsons. The division is based around a core of Redmondite National Volunteers, and Hickie, a Catholic and a home ruler, is an acceptable commander to John Redmond and other Irish nationalists.

Hickie is professional, politically adept, and popular with his men, and under his leadership the 16th is renowned for its aggressive fighting spirit. He commands the division during the Battle of the Somme in 1916 and, while proud of his men’s success in capturing Guillemont and Ginchy (September 1916), is appalled by their losses. When the division is ordered to capture Messines (now Mesen) in June 1917, he gives Major Willie Redmond permission to advance as far as the first objective and, following Redmond’s death, reproaches himself bitterly. After this attack the division is transferred to the fifth army and provides assault troops for future attacks. During the Third Battle of Ypres, and especially during the attack on Langemarck in August 1917, the division suffers horrendous casualties, losing 221 officers and 4,064 men. Among the casualties is Fr. Willie Doyle, who Hickie unsuccessfully recommends for a Victoria Cross. The division’s losses at Langemarck are highlighted by Irish MPs in the House of Commons, and Hickie’s handling of the attack is criticised. By this time, nationalist disillusionment with the war means that few Irish replacements are available, and Hickie is forced to accept increasing numbers of non-Irish conscripts into the division. Worn down by years of command, his health finally breaks, and, in February 1918, he is sent home on sick leave, being replaced by Major-General Sir Richard Amyatt Hull.

In 1918, Hickie is created a Knight Commander of the Order of the Bath (KCB) and is also awarded the French Croix de Guerre. During the Irish War of Independence (1919–21), he is critical of the methods used by Crown forces, denouncing in particular the indiscipline of the Black and Tans. In 1921 he retires from the army and becomes a prominent figure in the Royal British Legion in Ireland, tirelessly campaigning on behalf of ex-servicemen. In the 1920s he is involved with the Irish battlefield memorial committee, which erects memorial crosses at Wytschaete, Guillemont, and Salonika, commemorating the 10th and 16th divisions. He later serves as a senator of the Irish Free State (1925–36). Retiring from public life in 1936 to his residence at Terryglass, County Tipperary, he devotes his last years to gardening and reading.

Hickie dies on November 3, 1950, in Dublin, and is buried at Terryglass. He marries a daughter of the novelist Rev. J. O. Hannay, who predeceases him. There is a small collection of his papers in the National Library of Ireland (NLI).
