During the outbreak of
World War I, Robert Briscoe was living in
Berlin, but fled, using an American
passport issued by
U.S. Ambassador James W. Gerard, to join his parents at
Karlsbad, in the
Austro-Hungarian Empire. After being briefly interned as an
enemy alien at
Eger, Briscoe was released due to intervention of the
Papal Nuncio in
Vienna. He was also allowed to return to Dublin after swearing an oath that he would not take up arms against the
Central Powers. Briscoe, who had already been leaning towards
Irish republicanism, later recalled, "This I gladly did, since I had no desire to take part in England's wars." In what caused years of sharp political arguments with his father, Robert Briscoe rejected his Home Rule nationalist upbringing and instead embraced Irish republicanism. He was active with the Purchases Department, General Headquarters (GHQ) of the
Irish Republican Army (IRA) and
Sinn Féin during the
Irish War of Independence. He once upset his father by leaving the family's dinner when the IRA summoned him to an emergency meeting on the feast of
Yom Kippur. During the winter of 1919–1920, Briscoe was promoted to the personal staff of
Michael Collins. Collins affectionately referred to Briscoe as, "my Jewman", and once posed as an Orthodox Jew with Briscoe's help, while in hiding from the police in Dublin's
Little Jerusalem. Briscoe also accompanied
Éamon de Valera to the
United States of America. He regularly spoke for the Sinn Féin cause at public meetings there and was adamant that being a "Hebrew" did not alter his Irishness or lessen his patriotism. At the same time, Briscoe later recalled in his memoirs that he sometimes felt afraid of having possibly broken the
Second Commandment by loving Ireland more than the
God of Israel. Due to his fluency in the
German language from his family's pre-WWI business connections, Collins ultimately issued orders through Irish Jewish
barrister Michael Noyk While in Germany Briscoe purchased arms and had them shipped to Ireland in small parcels. Although the British authorities were constantly searching ships, smaller consignments of weapons were rarely discovered. In December 1920,
Charles McGuinness was made captain of a ship by the name the "Anita" and sent to the
Weimar Republic, where Briscoe had already purchased a large number of firearms. However, on the day the crew were due to depart for Ireland, McGuinness was observed by the port authorities paying the crew in large notes, which aroused their suspicions. The German police arrested McGuinness and the rest of the crew. McGuinness was brought to trial, but Briscoe paid for a good lawyer on McGuinness' behalf. Before a sympathetic German court, McGuinness' gun-running against the
British Empire was deemed to be a minor offence and he was charged a token fine of 2,000
Deutschmarks. After passing sentence, the German judge wished McGuinness, "better luck next time". The incident caused an uproar back in the United Kingdom. Other sources cite this shipment as "the largest military shipment ever to reach the I.R.A." consisting of 1500
Gewehr 98 rifles, 2000
Mauser C96 pistols, and 1.7 million rounds of ammunition. On 2 November 1921 the Frieda successfully landed its cargo near Waterford harbor. Also, during his assignment in
Berlin, Briscoe first came into conflict with and complained to his superior
John Smith Chartres about fellow Sinn Féin envoy
Charles Bewley. Bewley's tendency towards regularly spouting, "extremely derogatory remarks about Jews in general", even in public places, caused very serious problems for the legation, particularly after one such outburst in a Berlin cafe caused Bewley to be ejected by the outraged
German Jewish proprietor. At the insistence of Briscoe and multiple gentile members of the Irish Legation, Chartres wrote to the
Irish Foreign Office and requested that Bewley to be recalled to Dublin, which he described as, "in the interest of decorum, national dignity, and commercial prudence". Chartres further explained, "Moreover, an anti-Semitic outburst by an Irish official in a country where Jews are very numerous and very influential was an extraordinary indiscretion from the point of view of the Irish material interest." Bewley, however, had friends in high places and was not recalled until much later. ==Irish Civil War==
