In the wake of the Battle of the Somme and the repercussions of the Easter Rising, changes in Dublin’s engagement with the war were seen in four key areas from late summer 1916 into 1917 and the summer of that year. One was a renewal of recruiting efforts to fill gaps in the ranks. Two others – mounting front-line losses and manifestations of the war on the home front – demonstrated how the war was increasingly attritional. The other, the release in June 1917 of the remaining Easter Rising prisoners, gave a new impulse to republican politics in the city.
