Passage: The years between the Easter Rising of 1916 and the beginning of the War of Independence in 1919 were not bloodless. Thomas Ashe, one of the Volunteer leaders imprisoned for his role in the 1916 rebellion, died on hunger strike, after attempted force-feeding in 1917. In 1918, during disturbances arising out of the anti-conscription campaign, six civilians died in confrontations with the police and British Army and over 1,000 were arrested. Armistice Day was marked by severe rioting in Dublin, which left over 100 British soldiers injured. There were also raids for arms by the Volunteers, at least one shooting of a Royal Irish Constabulary policeman and the burning of an RIC barracks in Kerry. In Co. Cork, four rifles were seized from the Eyeries barracks in March 1918 and men from the barracks were beaten that August. In early July 1918, Volunteers ambushed two RIC men who had been stationed to stop a feis being held on the road between Ballingeary and Ballyvourney in the first armed attack on the RIC since the Easter Rising - one was shot in the neck, the other beaten, and police carbines and ammunition were seized. Patrols in Bantry and Ballyvourney were badly beaten in September and October. The attacks brought a British military presence from the summer of 1918, which only briefly quelled the violence, and an increase in police raids. However, there was as yet no co-ordinated armed campaign against British forces or RIC.
