Titus, the new heir to the imperial throne, at last made his appearance before Jerusalem (February, 70), fully expecting that he would be able to force the city into submission; for it was almost a reproach to the Romans that this rebellious capital should have maintained her independence for four years. The prestige of the new imperial house seemed in some measure to depend upon the fall of Jerusalem; a protracted siege would necessarily imply weakness in the military power of Vespasian and his son.
Although Titus was eagerly looking forward to the subjection of Judæa, he could not complete his preparations for the siege of Jerusalem before the spring. He collected an army of not less than eighty thousand men, who came, bringing with them the largest number of battering machines that had been used in the warfare of that time. Three traitors amongst the Judæans were most useful to him in his laborious undertakings—King Agrippa, who not only brought a contingent of men, but who also tried to influence the inhabitants of Jerusalem in favor of the Romans; Tiberius Alexander, who sealed his apostasy from Judaism by going into battle against his own nation; and Josephus, the constant companion of Titus, who, from being a prisoner, had become a guide in the country which he knew so well. Titus was not experienced enough in the art of war, and so bade the Judæan apostate stand by his side, and gave him the command of his own body-guard (Præfectus prætorio). But the hostile factions had drawn together when this new danger threatened them. Shortly before the Passover festival numbers of devoted men streamed into Jerusalem to defend their holy city. The elders and chiefs had sent messengers to the people living in the outlying provinces, praying for help, and their request was not made in vain. The walls of Jerusalem were fortified more strongly than ever.
At last Titus assembled his huge army from all sides and encamped at Scopus-Zophim, north of Jerusalem. He summoned in the first instance the inhabitants to surrender; he demanded only submission, acknowledgment of the Roman rule, and payment of the taxes. Eager as he was to return to Rome, where all the enjoyments belonging to his great position were awaiting him, he was ready to deal gently with the Judæans. Besides which, his devotion to a Judæan princess, who, in spite of her errors, still clung faithfully to the holy city, made him anxious to spare that city from destruction. But the Judæans refused all negotiation. They had sworn to defend their city with their lives, and would not hear of surrender. Then the siege began in earnest. All the gardens and groves to the north and west of Jerusalem, the first points of the attack, were unsparingly destroyed.
Titus, anxious to reconnoitre the ground, advanced with a few followers to the north wall, where he narrowly escaped being taken prisoner. The first feat of arms upon the part of the Judæans was crowned with success, and seemed a good omen for the future. A few days later they surprised and totally discomfited the Tenth Legion, who were pitching their tents on the Mount of Olives. But, unfortunately, this skirmish proved fruitless, for the Judæans were always obliged to retreat to their fortresses, not, however, without having convinced the Romans that they would have a desperate foe to encounter. The besiegers succeeded in pitching their camps on three sides of the city, and in raising their engines against the outer wall. Titus commenced operations during the Passover festival (March or April, 70), when he believed that the Judæans would not be willing to fight. But as soon as the engines were in working order, they rushed like demons from their retreat, destroying the battering-rams, scattering the workmen, and bringing alarm and confusion upon the enemy. Not only the Zealots, but all who could carry arms took part in the defense, the women setting splendid examples of heroism to the men. The besieged threw masses of stone upon their assailants, poured boiling oil upon their heads, seized the ponderous missiles that were hurled into the city, and turned them into tools of destruction against the Romans. But the latter succeeded in repairing their broken battering-rams, and in forcing the Judæans, after fifteen days of conflict, back from the outer wall. This wall, the scene of a desperate struggle, was at last taken by the Romans, who, while making themselves masters of it, seized the suburban town of Bezetha.
The skirmishes were now carried on daily, and with increasing bitterness. After seventeen days of unremitting labor, the Romans succeeded in raising their banks opposite the Antonine tower. But John of Gischala and some heroic followers of Bar-Giora, creeping through a subterranean passage, destroyed these works by setting fire to them. With the ever-increasing danger grew the heroism of the besieged. All Josephus' persuasive words, prompted by Titus, were useless. There were but two courses left open to them—victory or death. At the very outset of the siege they had learned what they would have to expect from the Romans. Titus, surnamed "Delight of all Mankind," crucified, at times, five hundred of his prisoners in a day. Again, he would send them back into the city after cutting off their hands. He was, however, forced to acknowledge to himself that the siege would be one of long duration. But the horrors of famine were soon to come to his assistance. All egress from and ingress into the besieged city being rigorously prevented, the provisions began to fail amongst the thickly-crowded populace. Houses and streets were filled with unburied corpses, and the pangs of starvation seemed to destroy all feelings of pity in the unfortunate survivors. The prospect—a terrible one indeed—of a lingering death sent numbers of deserters to the Romans, where they met with a pitiful fate. As the number of these unfortunate fugitives increased, the Zealots treated those whom they suspected of defection with still greater severity. A conspiracy being discovered amongst Bar-Giora's followers, that leader relentlessly punished the guilty with death. They were all beheaded in full view of the Roman camp, amongst them being Matthias Boëthus, of priestly family.
But in spite of the watchfulness of the Zealots, they were unable to circumvent the traitors in all their designs. Those who were secretly friendly to Rome shot off on their arrow-heads written accounts concerning the state of the city, which fell into the enemy's camp. The Zealots struggled manfully to prevent the Romans from completing their earthworks, but at the end of twenty-one days, the battering-rams were again pointing at the Antonine tower. The wall surrounding the fortress fell at length under the tremendous blows from without. What was the surprise and horror of the Romans, however, when they discovered that a second and inner wall had been erected behind the one they had succeeded in destroying. They tried in vain to storm it, the Judæans repulsing a nocturnal attack. The battle lasted until the following morning. It was at about this time that the daily sacrifices ceased, on account of the scarcity of the animals. Titus seized this opportunity again to summon the besieged to surrender, but the mere sight of the interpreter who bore the message aroused the indignation of the besieged. John of Gischala replied that the holy city could not be destroyed, and that God held her fate in His hands. The Judæans then withdrew to their last point of defense, the Temple. The battering-rams were raised against the sacred walls. The unfortunate people were compelled to destroy the colonnades leading to the Antonine tower, thus cutting off all connection with that fortress. They spared no craft to tire out the Romans, even setting fire to some of the pillars attached to the Temple, and then pretending to take flight. This stratagem succeeded in making the Romans climb over the walls, beyond which the Judæans lay in ambush to receive them, putting them to the sword or casting them into the flames. But the fire could not be extinguished, and the beautiful colonnade of the western side was entirely destroyed.
Meanwhile, the inhabitants of the city were suffering cruelly from famine, which was sapping their life, obliterating all distinctions between rich and poor, and giving free scope to the lowest passions. Money had lost its value, for it could not purchase bread. Men fought desperately in the streets over the most loathsome and disgusting food, a handful of straw, a piece of leather, or offal thrown to the dogs. The wealthy Martha, wife of the High Priest Joshua ben Gamala, whose wont it had been to step on carpets from her house to the Temple, was found searching the town like the very poorest for a morsel of food, of even the most revolting description. As if not one line of the old prophecy concerning the doom of Judæa was to remain unfulfilled, a terrible scene was enacted, which struck even the enemy with horror. A woman by the name of Miriam, who had fled from Peræa to the capital, actually killed and devoured her own child.
The rapidly increasing number of unburied corpses made the sultry summer air pestilential, and the populace fell a prey to sickness, famine, and the sword. But the army of the besieged fought on with unbroken courage, they rushed to the battle-field, although fainting with hunger and surrounded by grim pictures of death, as bravely as had been their wont in the early days of the siege. The Romans were amazed at the unflinching heroism of the Zealots, at their devotion to the Sanctuary and to the cause of their people. In fact, they grew to look upon them as invincible, and stimulated by this belief, some few of their number were actually known to desert their colors and their faith and to accept Judaism, persuaded, in their turn, that the holy city could never fall into the hands of the enemy. Proud as the Judæans well might be of these voluntary proselytes, at this the supreme moment of their history, they volunteered to guard them as best they could from the horrors of starvation.
Meanwhile, the Romans had begun to batter the outer walls of the courts of the Temple. For six days they had been working in vain, and had then tried to fix their scaling ladders and storm the walls. But as they were repulsed with great loss of life, Titus relinquished his hope of sparing the sacred edifice, and ordered his men to set fire to the gates. For a whole night and the next day the fire raged fiercely; then Titus commanded that it should be extinguished, and that a road should be leveled for the advance of his legions. A council of war was hastily summoned to decide upon the fate of the Sanctuary. This council consisted of six of the chief generals of the army, three of whom advised the destruction of the Temple, which, if spared, would inevitably remain as a focus for rebellion. Titus was opposed to this decision, partly on account of the Princess Berenice's feelings, and three of the council agreeing with their leader, it was decided to take the Temple, but not to destroy it.
On the 9th Ab, the Judæans made another desperate sally, but were driven back by an overpowering force of the besiegers. But the hour of the city's doom was about to strike, and in striking, leave an echo that would ring through the centuries to come. The besieged attempted one more furious onslaught upon their enemies. They were again defeated, and again driven back to their sheltering walls. But this time they were closely followed by the Romans, one of whom, seizing a burning firebrand, mounted upon a comrade's shoulders, and flung his terrible missile through the so-called golden window of the Temple. The fire blazed up; it caught the wooden beams of the sanctuary, and rose in flames heavenwards. At this sight the bravest of the Judæans recoiled terror-stricken. Titus hurried to the spot with his troops, and shouted to the soldiers to extinguish the flames. But no one heeded him. The maddened soldiery plunged into the courts of the Temple, murdering all who came within their reach, and hurling their firebrands into the blazing building. Titus, unable to control his legions, and urged by curiosity, penetrated into the Holy of Holies.
