Colonel Assheton had been called away from the siege early in April. After the sortie of April 26, the discouragement of the Parliamentarian troops was great, and Rigby wrote in much depression to the Committee at Manchester. "We are obliged to repel them five or six times in a night. These constant alarms, the numbers of the garrison, and our great losses, compel our men to mount guard every other night and even two nights in succession. For my part I am spent with anxiety and fatigue."[131] It is therefore surprising to find that summonses for surrender were still being sent into Lathom. The very day before the capture of the mortar a demand was sent to the Countess "to yield up Lathom House, all the persons, goods and arms within it to receive the mercy of the Parliament, and to return her final answer the next day before 2 o'clock." It was to this summons which Lady Derby returned her famous answer--
"Tell that insolent rebel, he shall neither have persons, goods nor house; when our strength and provision is spent, we shall find a fire more merciful than Rigby, and then if the providence of God prevent it not my goods and house shall burn in his sight; myself, children and soldiers rather than fall into his hands, will seal our religion and loyalty in the same flame."
This heroic declaration roused the garrison to wild enthusiasm, and they broke out into loud exclamations "we will die for His Majesty and your honour. God save the King."[132]
After this very little was done before Lathom for some weeks, though skirmishing continued at intervals with varying success. The Parliamentarians now confined themselves to a blockade of the House, and even this was not very effective. For five or six weeks before the end of the siege there seems to have been practically no fighting. The besiegers continued at work in their trenches, but a heavy fall of rain which caused some of the earth to fall in and killed three men, interfered with this undertaking. The royalists stated, and probably with some truth, that the besiegers were so disheartened that they could not prevent their men from deserting in large numbers.
At a meeting of the Committee in Manchester on April 23rd, it was resolved to raise additional troops for the siege at Lathom, and to assess a weekly amount of £4,627/6/4 on the whole county, except Lonsdale Hundred and Garstang Parish, which were already being taxed to maintain the siege of Greenhalgh Castle.[133] It is improbable, however, that these resolutions were carried into effect, for the attack showed no more vigour than before; and it had little prospect of success long before the approach of Prince Rupert effected a complete change in the position of affairs. It was not till towards the end of May that news came of Rupert's march, and Colonel Rigby again sent a summons to Lathom to surrender. This was of course refused; and the same day a messenger arrived from the Earl of Derby with news of the Prince's approach. This was, as a matter of fact, only two days before Rupert crossed the Mersey, and as soon as this was ascertained, the Parliamentarian troops marched away from Lathom with all haste. (May 27.) The royalists claimed that the besiegers had lost 500 men during the siege.[134]
