A regular cannonade was now kept up on both sides; but, though the shot occasionally fell inside the town, the danger to the inhabitants from this source was but slight; for, of the six guns possessed by the besiegers, five were very small, and one only was large enough to carry shell. All day the various chapels were open, and here the preachers, by their fiery discourses, kept up the spirits and courage of the people who thronged these buildings. The women spent most of their time there, and the men, when off duty from the walls, however fatigued they might be with their labour, flocked at once to the chapels, to pray for strength to resist and for early succour. Never were the whole population of the town more deeply animated by religious excitement, never a whole population more thoroughly and unanimously determined to die, rather than surrender.

When not upon the walls or in chapel, John spent much of his time in amusing the children, of whom there were many in the tanner's house. The change from their country quarters, the crowded town, the privation of milk, and the scantiness and unfitness of their rations, soon began to tell upon the little ones, and John felt thankful, indeed, that his mind had been stored with stories from his varied reading of the last two or three years. With these, he was able to interest and quiet the children, who sat round him with wrapt attention, while the booming of the guns and the occasional rattling of musketry outside passed unheeded.

Scarce a day passed without active fighting, the initiative being always taken by the besieged, for, in the royal army, the policy of blockade rather than assault was steadily adhered to. The besieged, however, continually sallied out, and attacked the parties engaged in throwing up works. There was no settled plan of operations; but the commander on each portion of the walls led out his men against the enemy, whenever he thought he saw a favourable opportunity. The fights which ensued were stoutly contested, and many were killed, but no advantage was gained on either side. If it was the intention of the besieged to incite the Royalists to make an attack upon the city, they failed altogether, and, indeed, would have served their purpose better had they remained quietly within the walls, for the energy and desperation with which they fought were well calculated to deter even the most energetic commander from attacking a town defended by eight or nine thousand men, animated by such fiery energy.

So confident, indeed, were the besieged, that the gates were often left open, and taunting invitations to come on and take Derry were shouted to the besiegers. The supply of provisions found to be stored away was vastly greater than had been expected, for many of the fugitives had brought in large stores, and a great number of the inhabitants had been, for weeks, making preparation for the siege, by buying up quantities of grain and storing it in their cellars.

Thus, up to the end of the first month, although the allowance of food was short, no real suffering was undergone by the inhabitants; but, as time went on, the supplies doled out became smaller and smaller, and dysentery and fever broke out in the crowded town.

Fierce disputes arose between those belonging to the Established Church and the Nonconformists, and it was with the greatest difficulty that Governor Walker prevented the two parties from engaging in open strife. Day and night, the besiegers' fire continued, and many were killed by the shells which fell in the city. The fighting men on the walls were far better off than those who had nothing to do but to wait and suffer, and it was among the women and children, chiefly, that disease at first made its victims.

For a time, the children of the families who had taken refuge with the tanner remained healthy. The visitors were lodged for the most part in the cellars, so as to be in shelter from the fire of the enemy's mortar; but John Whitefoot suggested to his cousin that the children would soon pine and sicken, unless they had air. The tanner gave his consent to John's establishing a shelter in the yard. A corner was chosen, and a number of casks were placed along by either wall; on these beams were laid, for it happened that the tanner had intended, shortly before the siege, to build a large shed, and had got the timber together for the purpose.

On the timber, bark from the now disused pits was heaped to a depth of some feet, which would effectually break the fall of any shell which might light upon it, and, along the front of this low triangular building, two lines of sacks filled with tan were placed. These would suffice to prevent any fragment of a shell, which might fall and burst in the courtyard, from entering the shelter; save by the opening, about a foot deep, between the top of the sacks and the beams.

When the whole was completed, John gathered the children there, and made it their headquarters, and established himself as captain of the castle, as he called it.

The elders entered warmly into his plans. It was a great relief, to them, to have the house cleared of the eighteen or twenty children. Their mothers had no longer any anxiety for their safety, and the children themselves looked upon it as great fun. There was plenty of air here, and, in a short time, John persuaded the parents to allow the children to sleep, as well as to pass the day, in the shelter. Here he told them stories, constructed toys for them, and kept them amused and quiet, appointing as his lieutenants three or four of the oldest of the girls, who had the little ones under their special charge. John was rewarded, for his pains, by seeing that the children kept their health far better than did those of their neighbours, and, up to the end of May, not one of them had succumbed, although several of the parents had already fallen victims to dysentery and fever.
