The 8th and 9th Dublins, who had arrived in France in December 1915 as part of the 48th Brigade in the 16th (Irish) Division, were also subject to a German gas attack at the Battle of Hulluch, near Loos, on 27 April 1916, suffering heavy casualties. There had been trouble at home that month in Dublin when the Easter Rising had taken place though, in spite of this, the Dublin Fusiliers still performed with dedication to their duty. The British launched the Somme offensive on 1 July and the 1st and 2nd Dublins took part in the First day on the Somme that saw the British forces sustain horrific casualties, some 60,000, about 20,000 of which were killed. The 8th and 9th Dublins took part in their first major battle during the Somme Offensive, taking part in the capture of Ginchy on 9 September, in which Lieutenant Tom Kettle fell in action. The Dublins also took part in the last major battle of the offensive, at the Ancre that took place between 13–18 November. The Dublins, once again, had suffered large numbers of casualties during the Somme offensive.
