The 1710 Spanish campaign opens on May 15 when the Spanish Bourbon army commanded by Philip V in person and Francisco Castillo Fajardo, Marquis of Villadarias, advance on the town of Balaguer. Guido Starhemberg, commander of the Allied forces in Catalonia, halts this attempt by preventing the Spanish from fording the Segre River, a success in which the officers of the British contingent have a leading role.
Having received reinforcements, in June Philip makes another attempt upon Balaguer with 20,000 infantry and 6,000 cavalry but is defeated at Almenar on July 27. The allied troops take up a strong defensive position and repel the Spanish attacks until the British commander, James Stanhope, leading their vanguard, breaks the Spanish lines. Philip is forced to withdraw to Zaragoza, capital of Aragon, while Villadarias is replaced by the French general Alexandre Maître, Marquis de Bay.
On August 9, the Spanish army reaches Zaragoza and de Bay positions his troops with the river Ebro on his left and the Torrero heights to the right. On August 15, an Allied cavalry attack is repulsed, followed by five days of minor skirmishes before the Allies cross the Ebro in force on August 19 and are allowed to deploy during the night.
The two forces are roughly equal in strength, the allies having thirty-seven battalions of infantry and forty-three squadrons opposed to the Spanish-Bourbon army of thirty-eight battalions and fifty-four squadrons. The Allied left, composed of Catalonian and Dutch troops, is led by Pedro Manuel de Ataíde, 5th Count of Atalaia, the right by Stanhope, made up of British, Portuguese and Austrian cavalry, with Starhemberg in charge of the centre, mainly German, Austrian and Spanish infantry.
On August 20 at 8:00 a.m., an artillery-duel starts which lasts four hours before Stanhope charges the Bourbon-Spanish left. At first the Spanish and Walloon troops of the Bourbon army seem to gain the advantage, having defeated a body of eight Portuguese squadrons, which they chased from the field. This opens a gap in the Bourbon lines, which opens a gap for Stanhope who scatters the disorganized Spanish soldiers, while at the centre and the right their attacks are repulsed.
The battle follows the same pattern as at Almenar, with the allies repulsing fierce Bourbon cavalry charges before counter-attacked with their infantry and pushing the Spanish back. In less than three hours, the Allies army wins a comprehensive victory, capturing the Bourbon artillery along with 73 standards. Between 5,000 and 6,000 Spanish soldiers are killed or wounded, and another 7,000 captured, with Allied losses estimated as 1,500 men dead or wounded.
Archduke Charles enters Zaragoza the next day. The defeat of the army of Philip V of Spain is severe, the way to Madrid is open. Philip V abandons Madrid on September 9 and goes to Valladolid. Archduke Charles enters a very hostile and almost empty Madrid on September 28. Charles comments, “This city is a desert!” In the winter of 1710, Archduke Charles and the allied troops have to abandon Madrid, due to the great opposition of the people of Madrid and the dangerous strategic situation. After this, the British army suffers a defeat at the Battle of Brihuega, and the rest of the allied army is defeated at the Battle of Villaviciosa.
O’Riordan joins the Communist Party of Ireland in 1935 while still in the IRA and works on the communist newspaper The Irish Workers’ Voice. In 1937, following the urgings of Peadar O’Donnell, several hundred Irishmen, mostly IRA or ex-IRA men, go to fight for the Spanish Republic in the Spanish Civil War with the XVth International Brigade. They are motivated in part by enmity towards the 800 or so Blueshirts, led by Eoin O’Duffy who go to Spain to fight on the “nationalist” side in the Irish Brigade. He accompanies a party led by Frank Ryan. In the Republic’s final offensive of July 25, 1938, he carries the flag of Catalonia across the River Ebro. On August 1, he is severely injured by shrapnel on the Ebro front. He is repatriated to Ireland the following month, after the International Brigades are disbanded.
In 1938 O’Riordan is offered an Irish Army commission by the Irish Free State but chooses instead to train IRA units in Cork. As a result of his IRA activities during World War II, or the Emergency as it is known in neutral Ireland, he is interned in the Curragh internment camp from 1939 until 1943 where he is Officer Commanding of the Cork Hut and partakes in Máirtín Ó Cadhain’s Gaelic League classes as well as publishing Splannc (Irish for “Spark,” named after Vladimir Lenin‘s newspaper).
In 1944 O’Riordan is founding secretary of the Liam Mellows Branch of the Labour Party and in 1945 is a founding secretary of the Cork Socialist Party, whose other notable members include Derry Kelleher, Kevin Neville and Máire Keohane-Sheehan.
In 1947, O’Riordan is a founding secretary of the Irish Workers’ League and general secretary thereafter, and of its successor organisation the Irish Workers’ Party from 1962–70.
In all O’Riordan runs for election five times, campaigning throughout for the establishment of a socialist republic in Ireland but given Ireland’s Catholic conservatism and fear of communism, he does so without success. He does, however, receive playwright Sean O’Casey‘s endorsement in 1951.
O’Riordan’s participation in the Spanish Civil War is always an important part of his political identity. In 1966 he attends the International Brigades’ Reunion in Berlin and is instrumental in having Frank Ryan’s remains repatriated from Germany to Ireland in 1979.
O’Riordan is a member of the Irish Chile Solidarity Committee and attends the 1st Party Congress of the Communist Party of Cuba in 1984. He also campaigns on behalf of the Birmingham Six and attends their Appeal trial in 1990. He serves as General Secretary of the Communist Party of Ireland (1970–83) and as National Chairman of the party (1983–88). He publishes many articles under the auspices of the CPI.
O’Riordan’s last major public outing comes in 2005 at the re-dedication of the memorial outside Dublin’s Liberty Hall to the Irish veterans of the Spanish Civil War. He and other veterans are received by President of IrelandMary McAleese. He is also presented with Cuba’s Medal of Friendship by the Cuban Consul Teresita Trujillo to Ireland on behalf of Cuban President Fidel Castro.
In 1969, according to Soviet dissident Vasili Mitrokhin, O’Riordan is approached by IRA leaders Cathal Goulding and Seamus Costello with a view to obtaining guns from the Soviet KGB to defend Irish republican areas of Belfast during the communal violence that marks the outbreak of the Troubles. Mitrokhin alleges that O’Riordan then contacts the Kremlin, but the consignment of arms does not reach Ireland until 1972. The operation is known as Operation Splash. The IRA splits in the meantime between the Provisional IRA and the Official IRA and it is the latter faction who receives the Soviet arms. Mitrokhin’s allegations are repeated in Boris Yeltsin‘s autobiography.
O’Riordan’s book, Connolly Column – The Story of the Irishmen who fought for the Spanish Republic 1936–1939, is published in 1979 and deals with the Irish volunteers of the International Brigade who fought in support of the Spanish Republic against Francisco Franco in the Spanish Civil War (1936–1939). An updated version of the book is reprinted in 2005 and is launched by the Lord Mayor of Dublin, Cllr. Michael Conaghan at a book launch at SIPTU headquarters, Liberty Hall. The book is the inspiration for Irish singer-songwriter Christy Moore‘s famous song “Viva la Quinta Brigada.”
In 1991, O’Riordan’s wife dies at the age of 81 at their home. He continues to live in their family home before moving to Glasnevin in 2000 to be close to his son Manus who lives nearby. He lives there until falling ill in November 2005 and is taken to the Mater Hospital. His health rapidly deteriorates, and he quickly develops Alzheimer’s disease. Soon afterwards he is moved to St. Mary’s Hospital in the Phoenix Park where he spends the final few months of his life, before his death at the age of 88 on May 18, 2006.
O’Riordan’s funeral at Glasnevin Crematorium is attended by over a thousand mourners. Following a wake the previous night at Finglas Road, hundreds turn up outside the house of his son Manus and traffic grounds to a halt as family, friends and comrades – many of whom are waving the red flag of the Communist Party of Ireland – escort O’Riordan to Glasnevin Cemetery. A secular ceremony takes place led by Manus O’Riordan, Head of Research at SIPTU, with contributions from O’Riordan’s family, Communist Party general secretary Eugene McCartan and IBMT representative Pauline Frasier.
