On landing in Dublin, the general made a speech to the people, in which he spoke of his purpose as "the great work against the barbarous and bloodthirsty Irish, and all their adherents and confederates, for the propagating of the gospel of Christ, the establishing of truth and peace, and restoring that bleeding nation to its former happiness and tranquillity." His first act was to remodel the Irish army, making "a huge purge of the army which we found here: it was an army made up of dissolute and debauched men"; and the general issued a proclamation against swearing and drunkenness, and another against the "wickedness" that had been taken by the soldiery "to abuse, rob, and pillage, and too often to execute cruelties upon the country people," promising to protect all peaceable inhabitants, and to pay them in ready money for all goods. Two soldiers were shortly hanged for disobeying these orders.
Having made a general muster of his forces in Dublin, and formed a complete body of fifteen thousand horse and foot, he selected a force of ten thousand stout, resolute men, and advanced on Drogheda (in English, Tredagh). Drogheda is a seaport town on the Boyne, about twenty-three miles due north of Dublin. It was strongly fortified, and Ormonde,[41] as Clarendon tells us, had put into it "the flower of his army, both of soldiers and officers, most of them English, to the number of three thousand foot, and two or three good troops of horse, provided with all things." Sir Arthur Ashton, an English Catholic, an officer "of great name and experience, and who at that time made little doubt of defending it against all the power of Cromwell," was in chief command.
Cromwell's horse reached Drogheda on September 3d, his memorable day; some skirmishes followed, and on the 10th the batteries opened in earnest, after formal summons to the garrison to surrender. A steeple and a tower were beaten down the first day; all through the 11th the batteries continued, and at length effected "two reasonable breaches." About five in the evening of the second day the storm began. "After some hot dispute we entered, about seven or eight hundred men; the enemy disputing it very stiffly with us." But a tremendous rally of the garrison—wherein Colonel Castle and other officers were killed—drove out the column, which retreated disheartened and baffled. Then the general did that which as commander he was seldom wont to do, and which he passes in silence in his despatches.
"Resolved," says Ludlow, "to put all upon it, he went down to the breach; and calling out a fresh reserve of Colonel Ewer's men, he put himself at their head, and with the word 'our Lord God,' led them up again with courage and resolution, though they met with a hot dispute." Thus encouraged to recover their loss, they got ground of the enemy, forced him to quit his intrenchments, and poured into the town. There many retreated to the Millmount, a place very strong and difficult of access; "exceedingly high and strongly palisaded." This place commanded the whole town: thither Sir Arthur Ashton and other important officers had betaken themselves. But the storming party burst in, and were ordered by Cromwell to put them all to the sword. The rest of the garrison fled over the bridge to the northern side of the town; but the Ironsides followed them hotly, both horse and foot, and drove them into St. Peter's Church and the towers of the ramparts.
St. Peter's Church was set on fire by Cromwell's order. He writes to the speaker: "Indeed, being in the heat of action, I forbade them to spare any that were in arms in the town: and I think that night they put to the sword about two thousand men." Next day the other towers were summoned, and the work of slaughter was renewed for two days, until the entire garrison was annihilated. It was unquestionably a massacre. "That night they put to the sword about two thousand men." In St. Peter's Church "near a thousand of them were put to the sword, fleeing thither for safety." "Their friars were knocked on the head promiscuously." "I do not think we lost a hundred men upon the place." Such are a few passages from Cromwell's own despatches.
The slaughter was indeed prodigious. The general writes: "I believe we put to the sword the whole number of the defendants. I do not think thirty of the whole number escaped with their lives." "The enemy were about three thousand strong in the town." "I do not believe, neither do I hear, that any officer escaped with his life, save only one lieutenant." He subsequently gives a detailed list of the slain, amounting to about three thousand. Hugh Peters, the chaplain, reports as follows:
"Sir, the truth is, Drogheda is taken, three thousand five hundred fifty-two of the enemy slain, and sixty-four of ours. Ashton the governor, killed, none spared." It is also certain that quarter was refused. "I forbade them to spare any that were in arms in the town." It is expressly told us that all officers and all priests taken were killed. From the days of Clarendon it has been repeated by historians that men, women, and children were indiscriminately slaughtered, and there is evidence of an eye-witness to that effect; but this is not believed to have been done by the order, or even with the knowledge, of the general. The Royalist accounts insist that quarter was promised at first; and that the butchery of men in cold blood was carried on for days. Here again the act must have been exceptional and without authority.
To Cromwell himself this fearful slaughter was a signal triumph of the truth. "It hath pleased God to bless our endeavors." "This hath been a marvellous great mercy." "I am persuaded that this is a righteous judgment of God upon these barbarous wretches, who have imbrued their hands in so much innocent blood; and that it will tend to prevent the effusion of blood for the future. Which are the satisfactory grounds to such actions, which otherwise cannot but work remorse and regret." "It was set upon some of our hearts, That a great thing should be done, not by power or might, but by the Spirit of God." In the same sense it was received by Parliament and council of state, by some of the noblest spirits of their age.
Ludlow says simply that this "extraordinary severity was used to discourage others from making opposition." It had always been the policy of Cromwell in battle to inflict a crushing defeat; at Marston, at Naseby, and at Preston he had "taken execution of the enemy" for hours and over miles of country. At Basing and elsewhere, after a summons and a storm, he had slaughtered hundreds without mercy. And such was the law of war in that age, practised on both sides without hesitation. But the item of numbers and of time tells very heavily here. The killing of hundreds in hot blood differs from the massacre of thousands during days.
There was no such act in the whole civil war as the massacre—prolonged for days—of three thousand men enclosed in walls entirely at the mercy of their captors, to say nothing of the promiscuous slaughter of priests, if not of women and unarmed men.
