Early in November,
Lord Moore of Mellifont had become concerned about the defense of Drogheda and had stepped in to make preliminary improvements. Among the actions that he took were to procure four guns and gunpowder from a merchant ship on the nearby
River Boyne. He transferred the guns to the town and placed them on Mill Mount. Lord Moore then put the people of Drogheda to work reinforcing weak points in the city walls. Through appeal to the Lord Justices in Dublin, he was then able to secure a commission to enroll and equip 120 citizens of Drogheda as a military troop at the expense of the State. Lord Moore's actions and concerns eventually convinced the Lord Justices to appoint
Sir Henry Tichborne as the Governor of Drogheda. On 8 November, Sir Tichborne set out for Drogheda taking with him 1,000 reinforcements. After the arrival of the reinforcements, the military complement of the garrison at Drogheda had reached approximately 1,660. Because the rebel force had no
artillery with which to breach the walls of Drogheda, they surrounded the town hoping to starve the Royalists into submission. As the garrison continued to hold out throughout the four month siege, the rebels attempted to attack the walls and break into the city in a conventional manner. ==Aftermath==
