the second account

i came across is from the epic 13 volume ' The Great War ' edited by H.W Wilson published

 by Amalgamated Press Limited. It is headed ' Irish Heroism at Loos ' and reads:-

" Another exploit of great brilliance and much farther reaching importance was performed in Loos Salient on April 27th 1916. The rising of the Sinn Fein conspirators was then causing suffering and misery in Dublin and a violent band of Irish-German plotters in the United States was endeavouring to exaggerate the nature of the outbreak which they had organised and financed and make it out to be a movement of revolt with a national force behind it. But at this crisis when the German Emperor was trying to use Ireland both against President Woodrow Wilson in the dispute over submarine warfare and against the Allies generally, the German commander at Lille made a grave mistake. He enabled the real fighting men of Ireland to show beyond doubt and with instant energy for what cause they were ready to lay down their lives by ordering an attack upon that part of the British Line which was being held by an Irish Division.
The Irishmen were feeling uncommonly sore and moody, a few days before Sir Roger Casement had landed in
in their country- Casement who, as was alleged, had tried to seduce Irish prisoners of war in Germany from
"Brave Munsters Reply to German Insults "

Above, a romantic illustration from ' The War Illustrated ' dated 3rd June 1916 captioned ' Immediately after the news of the Dublin rebellion reached the German Lines, placards appeared in the enemy trenches opposite the Munsters bearing taunting messages to the effect that the English soldiers were shooting Irish women in Dublin. The insult so enraged the Munsters that a nocturnal raid on the placrads was organised. The first attempt was discovered by searchlights and several brave Irishmen were shot down by machine-guns. The Munsters however were not to be denied: they made a second dash, scattered the Germans right and left, and brought the placards back in triumph. ( Copyright SM )

their allegiance and had left them to be starved and otherwise ill-treated when they refused to fight for the spoilers of Belgium. Then to crown the sorrow of the Irish troops, the Sinn Fein rising had occurred. The Germans probably knew well what division it was that held the chalk-pit salient at Loos. The attack was one of those widly fatuous essays in psychology in which the laboriously blundering Teutonic mind delights. The Germans calculated that the Irish troops would be so upset and distracted by waht was happening in Ireland that they would not be able to hold their ground.
Day broke clear and bright over the angle of lines in the chalk-pit between Loos and Hulluch, but there was a gentle easterly breeze blowing. An easterly breeze was suspect, and though the enemy had attempted no serious gas attack for some months, there was no relaxation of defensive precautions in our lines. And this was well for some forty minutes after day broke a thick, sluggish greenish cloud rolled from the enemy's trenches on a front of more than a mile. " Poison gas! put on your helmets! " cried the Irish officers " I wish we could give Roger Casement a taste of it in his throat! " said one of the men.
Above left, British troops wearing an early form of protction against gas, prepare to repel a German attack. Right, the gas masks used in the above piece of film were far more advanced than those used by the Munster Fusiliers on the morning of the German attack. Indeed most of this footage was filmed later in the war. It does however show some interesting footage and some of the terrible injuries and side effects caused by the use of gas. ( depending on which type was used )

Quickly they put on their masks and the cloud of agonising death rolled over the Dublin Fusiliers and Inniskillings who held the fire-trenches and thinned out among their comrades in the rear. The sergeants walked among the men where the poison fume was thickest, patting them on the shoulder and making pantomatic fun of the Hunnish method of warfare. As the gas was passing over the enemy's artillery which had been pounding all night at the salient, poured a final smashing fire, and then lifted against the Irish support trenches and deluged them with blinding gas shells and shrapnel to prevent any reinforcement of the fire-trenches. Two Columns of German infantry stormed across the neutral zone ( No Mans Land ) The Dublin battalion was composed mainly of young troops who had not withstood an infantry attack, but, despite the gas cloud, the lachrymal shells and hurricane fire of high-explosive shells, the men had that within that kept them steady as veterans. Not a German got through what remained of the barbed-wire defence. The Dublins shot down both columns. Then on the Northern side of the chalk-pit salient, held by the Inniskillings the hostile commander launched another attack in the same fashion. First came a great gas cloud, followed by a terrific artillery bombardment and a curtain fire on the Irish support line. In this case the German gunners were more expert, for they broke down the parapet at the angle of the trenches, blowing away the sand-bags and completely smashing up the wire fence in front of the position. The second German infantry attack meeting with no obstacle whatever reached the first Irish line, and the Inniskillings with some of the Dublins, fell back down the communication trenches towards the support line. But when the Germans entered the destroyed fire-trench they had good cause to wish they were bacck in their own lines. The traverses as well as the parapets had been destroyed and the result was that an Irish machine-gunner, surviving in a good position along the line was able to enfilade the attackers and turn the trench they had won into a death-trap. In a very few minutes the Inniskillings returned with fixed bayonets. Their blood was up and they did their work with fierce speed and terrible neatness. It was a complete clean up, for most of the Germans who tried to escape from the Irish bayonets were caught by the macchine-gun near the end of the salient. Such was the answer of the true fighting men of Erin to the German and Germanised conspirators in Dublin and the United States. The enemy then tried a third gas attack, but when the cloud was floated the wind changed and swept it over the poison users. So the action ended with the balance of losses in effectives lying heavily against the Germans, while the victorious Irish Battalions still held the chalk-pit salient, which they rebuilt in the night and made stronger.
