Ireton came before Limerick on June 3 on the Clare side of the Shannon. A large number of cattle had been collected at a place called Ferboe, a little above the town, where there was a narrow pass partly defended by an old castle. A stout resistance was made here, but Ingoldsby forced the passage with his cavalry and drove the Irish back to Thomond Bridge, about 150 being killed or drowned. The cattle formed a welcome addition to the commissariat, and Ireton marched on without further opposition. The estuary was in the hands of the Parliament, and the next few days were spent in landing cannon and mortars. The word bomb was, perhaps, first applied to the mortar-shells used during this siege. June 18 was set apart as a day of thanksgiving 'for the Lord's mercies in bringing us over the Shannon,' and other unexpected successes, and on the next day Ireton having formally summoned Limerick, at once began the bombardment. A battery of twenty-eight guns played upon the castle defending Thomond Bridge. Two mortars, afterwards increased to four, threw shells into the town, but the largest, carrying projectiles of two hundred weight, burst, but without hurting anyone. Ludlow joined Ireton three days later, and found that a lodgment had already been effected on the great salmon-weir above Limerick, where a castle still stands. Two guns were brought to bear, and from one the first shot went in at a window and broke a soldier's leg. The garrison at once took to their boats, but the fire was so hot that they all rowed to shore and surrendered, some to Tothill on the Clare bank, and some to Ingoldsby on the Limerick bank.[209] [Sidenote: Ireton's justice.] Ireton, says Ludlow, 'was so great a friend of justice, even where an enemy was concerned, that, though Colonel Axtell was a person extraordinarily qualified ... he suspended him from his employment.' A court-martial had found that he killed prisoners who had been promised quarter by soldiers, though not by himself. This seems to have been in the attack on Meelick. Tothill was now charged with the same offence and deprived of his regiment, his ensign being also cashiered. Tothill pleaded that he thought no one could grant quarter but the commanding officer, and that the Lord Deputy would be angry if he showed mercy. Ireton said the punishment was too little for the offence and the excuses equally abominable, 'for the base and servile fear pretended in the latter part, as for the pride of spirit predominate in the former.' He was somewhat consoled by the fact that Ingoldsby spared all lives on his side.[210] [Sidenote: Fruitless negotiations, June.] [Sidenote: Non-combatants turned out of Limerick.] [Sidenote: Disaster to the besiegers, June 23.] [Sidenote: Ireton's explanation.]
