The fortifications in those days were very far from having attained the strength and solidity which a few generations later were bestowed upon them. The stones of which they were constructed were comparatively small, and fastened together by mortar, consequently they could ill resist even an assault by manual weapons. Covered by their shields the Northmen worked untiringly at the foundations, and piece by piece the walls crumbled to the ground. Every effort, however, to enter at the breaches so made was repulsed, and Siegfroi kept back his warriors, determined to delay the grand assault until the next day. By nightfall the tower was in ruins, scarce a portion of the walls remaining erect. Many of the besieged had been killed. The archbishop was wounded with an arrow. Frederic, a young soldier who led the troops of the church was killed.
The besiegers had suffered much more severely, great numbers having been killed by the stones and missiles hurled down by the defenders while engaged in the demolition of the walls. At nightfall the Danes carried off their wounded and recrossed the river, confident that next day they would succeed in their assault. As soon as darkness had set in Count Eudes collected the citizens, and these, bearing beams and planks, crossed the bridge to the tower, and set to work. Outside the circle of ruins holes were dug and the beams securely fixed. Planks were nailed to these, and earth heaped up behind them.
All night the work continued, and by morning a fortification much higher than the original tower had been erected all round the ruin. The Danes again crossed the river in their ships, and the assault was renewed. Javelins and great stones were hurled at the fortification, and clouds of arrows from the shipping fell within them. Covered with portable roofs constructed of planks the Danes strove to destroy the wall. The besieged poured upon them a blazing mixture of oil, wax, and pitch. Numbers of the Danes were burned to death, while others, maddened by the pain, threw themselves into the river.
Over and over again Siegfroi led his warriors to the attack, but the defenders, headed by Eudes and the brave Abbe Ebble, each time repelled them. The abbe particularly distinguished himself, and he is reported to have slain seven Danes at once with one javelin, a blow which may be considered as bordering on the miraculous. But the number of the defenders of the tower was small indeed to that of the enemy, and the loss which they inflicted upon the Danes, great as it was, was as nothing in so vast a host.
The flames of the machines, lighted by the pitch and oil, communicated to the planks of the fortification, and soon these too were on fire. As they burned, the earth behind them gave way, and a breach was formed. Encouraged by this result the Danes brought up faggots, and in several places lighted great fires against the fortifications. The defenders began to lose all hope, when a tremendous storm of rain suddenly burst over Paris quenching the fire.
The besieged gained heart, reinforcements crossed from the town, and the Danes again withdrew to their ships, having lost in the day's fighting three hundred men. After this repulse the Northmen desisted for a time from their attack. They formed a strong fortified camp near the church of St. Germain, and then spread over the country slaying and burning, sparing none, man, woman, or child. From the walls of Paris the smoke could be seen rising over the whole country, and every heart was moved with rage and sorrow.
Edmund and his party had taken no part in the defence of the tower. Its loss would not have involved that of the town, and Eudes requested him to keep his band in reserve in order that they might remain intact until the Danes should make a breach in the walls of the city itself, when the sudden reinforcement of a party of such well-trained warriors might decide the result.
While a portion of the Danish host were engaged upon the work of devastation, a large number were employed upon the construction of three great towers. These were built on wheels, and were each large enough to hold sixty men. They far overtopped the walls, and the citizens viewed with alarm the time when an assault should be delivered under the protection of these formidable machines. Eighteen ships of equal size were moored by the bank six deep. Great planks were laid across them, and a sloping platform having been formed, the towers were by the efforts of thousands of men moved up and placed on the ships.
"If we do not destroy those towers, Egbert," Edmund said one day as he saw them slowly moving into their position on board the ships, "all is lost, for from their summits the Northmen with their bows and javelins will be able to clear the walls, while those below effect a breach at their leisure."
"That is true enough, Edmund, but I do not see any way to destroy them. Unfortunately we have no boats, or we might fill some of them with combustibles, and tow them down until near enough for the stream to carry them upon those vessels; but even then the chance were small indeed, for the Danes would swarm out in their boats and manage to tow or push them so that they would not touch the ships."
