Machine guns swept right up Dame Street on the one hand and on the other through Westmorland Street as far up as O'Connell's Statue at the end of the bridge; but this was as far north as the military got, for all along to Clontarf, Glasnevin, and Drumcondra the insurgents held practically undisputed sway. Another minor position of great importance was the clearing of Stephen's Green by means of a maxim from the "Shelbourne." The first actual entry of the military in force from an outside area took place on Tuesday evening, when a body of Royal Dublin Fusiliers forced their way into the centre of the city by Cabra Road. The insurgents had placed barricades both on the Park Road and on Cabra Road, near the point at which Charleville Road links up these thoroughfares. Houses overlooking the barricades were occupied by the insurgents, and some brisk fighting took place before the way was cleared for the military advance. A well-directed shell or two demolished the barricades, and within a short time the defenders, under the thunder of artillery, machine guns and rifle-fire, were forced from these positions. There were a couple of civilian casualties resulting from the shrapnel. Attempts by the insurgents to blow up the Cabra Bridge and the bridge crossing the Midland Railway on the North Circular Road beyond Phibsborough Church were unsuccessful. It was not until Wednesday morning, as we have already seen, that the city realized that an attack in full force was contemplated, and if necessary heavy artillery would be used to dislodge the rebels. Up to that it had been thought that at the worst gas shells might be dropped upon the enemy strongholds and that the city would be spared: but it early became evident that the disproportion would be too great in the street fighting, which everyone now saw was becoming inevitable. Accordingly, during the early hours of Wednesday morning a party of six volunteers from Trinity--including both civilians and members of the O.T.C.--went forth to dig holes below the cobbles for the gun-trails. The position was at the Tara Street end of Butt Bridge, and the object, in order to be ready to begin early the shelling of Liberty Hall, which was looked upon as the centre and symbol of the anarchy. After much difficulty two 18-pounders were brought up and machine guns were placed on the tower of the Fire Station and the Tivoli, and then, when all was ready, the bombardment began. Evidently the rebels had got wind of this intention, however, and though much damage was done, practically no casualties were scored, the rebels getting away through the basement or along the roofs. The _Helga_, an old police patrol boat belonging to the Fisheries Department, next contributed, though the task was an extremely delicate one, owing to the position of the Custom House and the Railway Bridge, having eventually to retire further down the river and adopt a dropping instead of a direct fire.
