God's War: A New History of the Crusades

intentions towards the Greek empire; more shades of 1147. Only when Frederick agreed to continue negotiations by sending the requested new delegation did the Byzantine representatives commit their government to helping the crusaders with guides, markets, security and transport for the crossing to Asia Minor. The German envoys would help coordinate this assistance. Even so, Greek fear was hardly assuaged. So large an army, whatever its motives, would have the material effect of an invasion.

Despite Frederick’s energetic preparations, the need for haste was loudly proclaimed, not least by Henry of Albano, who lamented the backsliding of some crusaders and the in-fighting of others, which he likened to dogs returning to their own vomit.³¹ In fact, compared with the kings of England and France, Frederick moved with vigour and drive, at the head of a genuinely popular movement that redirected the lives and funds of nobles, their ministeriales and knights, lesser lords, higher and lower clergy, urban and rural elites and freemen from all parts of Germany. As a sympathetic contemporary noted, Frederick, ‘who had been the last king to make his vow of pilgrimage, hurried to be the first to discharge it’.³² The experience of 1147–8 prompted Frederick to maintain a very tight grip on his huge coalition. Twice on the march to Constantinople, he refined disciplinary ordinances for his disparate troops and non-combatants, establishing a system of justice and punishment sworn by the whole army and, later, dividing the host into self-regulating judicial units within this agreed communal system. In sharp contrast to Louis VII’s ordinances for his crusade army in 1147, Frederick’s were enforced. Loutish behaviour led to loss of hands; theft to execution. Such harsh discipline was coupled with a constant emphasis on the pious nature of the operation. At Vienna, Frederick purged the army of undesirable elements, including the prostitutes. The general effect on morale and military effectiveness stood in marked contrast to the shambles into which Conrad III’s army had descended in Asia Minor in the autumn of 1147. Frederick remembered. His army’s reputation for order and piety became notorious. Ibn Shaddad recorded a possibly genuine letter to Saladin by the Catholicos of the Armenian church in northern Syria, Gregory IV, written in 1190, which testifies at least to the nature and success of German propaganda if not their piety:

They are of varied races and strange ways. Their cause is a great one and they are serious in their enterprise and of prodigious discipline, so much so that, if one of them commits a crime, the only penalty is to have his throat cut like a sheep. I was informed about one of their nobles, that he did wrong to a page of his and beat him beyond the limit. The priests gathered to give judgement and the case by general decision demanded that his throat be cut. Many petitioned the emperor on his behalf, but he paid no attention and had his throat cut. They have forbidden themselves pleasures even to the extent that, if they hear that anyone has allowed himself any pleasure, they treat him as an outcast and chastise him. All this because of grief for Jerusalem.³³

The image of a ‘Christian militia’ fostered by Frederick’s later panegyrists may not simply have been a construct of preachers, observers and historians but, as on the First Crusade, an integral part of the army’s own mechanisms of self-regulation and morale. Chroniclers’ comparisons with the Theban legion and the Maccabees may have seemed appropriate to the troops themselves as they struggled across Asia Minor in the spring of 1190. In letters home in the autumn of 1189, Frederick himself described his followers as ‘the army of the Holy Cross’ or ‘of the life-giving Cross’, in clear association with the central image of the recruiting campaign.³⁴ This sense of identity and destiny underpinned the whole enterprise. The tone for the expedition had been set by the careful orchestration of Frederick’s adoption of the cross in March 1188 and his receiving the scrip and staff of a pilgrim at Hagenau in April 1189. However, throughout the German march, the maintenance of morale and a sense of purpose ran in tandem with Frederick’s careful planning and judicious use of force.

The German contingents for the land route mustered, as arranged, at Regensburg on 23 April 1189. On 11 May, the army or, more realistically, armies, moved off down the Danube, the high command in boats, the rest on shore. Progress was rapid and peaceful, past Vienna to Bratislava (Pressburg), where disciplinary regulations were promulgated. By 4 June the Germans reached Esztergom (Gran) on the Hungarian frontier. They were greeted with lavish hospitality by King Bela III and his wife Margaret. Poised between Byzantium and the west, Hungary’s involvement in crusading reflected an eagerness to be associated with Latin Christendom, not least as a means of ensuring independence. Queen Margaret, daughter of Louis VII of France, Frederick’s companion in arms on the Second Crusade, embodied this policy. More immediately, the Hungarians supplied the crusaders with provisions, equipment and access to plentiful if expensive markets. After what appeared, in retrospect at least, a comfortable passage through Hungary, the crusaders reached the Byzantine border at Branitz (Brnjica) on 2 July.

Relations with the Byzantine empire were complicated by Isaac II’s uneasy hold on his Balkan provinces, his need to secure his eastern frontier by a treaty with the Seljuk Turks, past tensions with the Germans in Italy, a tradition of hostility with Sicily, now allied with Frederick, and with the west more generally over Italian trading rights and Antioch.³⁵ There persisted a fear, especially among the Constantinopolitan elites, that all western armies held as an ulterior motive the conquest of the Greek empire. On the westerners’ side, the religious schism sharpened the feeling that the Greeks were poor Christians in their apparent indifference to the Holy Land. Isaac Angelus had acquired the throne in 1185 after a coup marked by mob sadism unusual even in Byzantium, the previous emperor Andronicus I Comnenus, himself a murdering usurper, being torn to pieces in the streets of the capital. Isaac balanced his political weakness with petulant diplomatic bluster. Having promised assistance to the Germans, in the summer of 1189 Isaac suddenly threw the German ambassadors he had asked for into prison. He continued to pursue amicable relations with Saladin, whom he kept informed of the German progress.³⁶ Saladin’s envoys were in Constantinople when the German ambassadors arrived and allegedly received the horses of the unfortunate westerners when they were incarcerated. It is hard to divine the immediate advantage for the Greeks in the Ayyubid alliance, a feature of Byzantine foreign policy after 1182. Isaac may have hoped to counteract any agreement Frederick had reached with the Sicilians or the Seljuks or use it as a lever to engineer recognition of suzerainty over Antioch and other former Greek territories that the crusaders conquered. Yet such hopes were fatally undermined by Isaac’s lack of adequate military strength to exert pressure on the crusaders. More immediately damaging was his failure to prevent the German army from being attacked more or less the entire length of their journey from the Danube to the plains of Thrace. The net result of Isaac’s policy, if such a farrago of myopic expedience and folly can be so described, was to provoke Frederick into contemplating precisely what the Greek feared most, an attack on Constantinople.

From Branitz, the Germans threaded their way to Nish, which was reached on 27 July. Given the awkward terrain and the length of the crusader marching line, the army was divided into four divisions.³⁷ Despite the persistent harassment from locals acting, many believed, on Isaac’s orders, Frederick was reluctant to throw in his lot with Serbian rebels who met him at Nish. The journey though Bulgaria to Sofia increasingly resembled a fighting march, familiar to eastern tactics and from the First and Second Crusades. At Sofia, on 13 August, the Germans found that the promised markets and currency exchange had been removed on imperial orders and that the route to the Maritsa valley and Thrace had been fortified against them. After battering their way through the mountains, on 24 August the crusaders reached Philippopolis, which had been abandoned by its inhabitants and its defences destroyed on Isaac’s orders by the governor of Thrace, the civil servant and historian Nicetas Choniates. Years later, in the shadow of the loss of Constantinople to the Fourth Crusade in 1204, Nicetas painted an intimate but unflattering portrait of Byzantine confusion, duplicity and impotence at this time.³⁸

By the time Frederick entered the deserted Philippopolis on 26 August, he had learnt of the arrest of his ambassadors in Constantinople and of Isaac’s demands for German guarantees of good behaviour and a share of future crusade conquests. Despite a growing problem of supplies, Frederick was in no mood to compromise, especially as he held a clear military advantage. Isaac’s diplomatic tactlessness, such as failing to afford Frederick his proper title in correspondence, soured relations further. While angry diplomatic exchanges continued, the release of the German ambassadors without what Frederick regarded as adequate reparations did little to resolve the central issue of Byzantine assistance in transporting the crusaders across into Asia Minor. Having occupied Philippopolis and the surrounding region, securing food and markets, by early November Frederick had decided on a strategy to force Greek cooperation.

Perhaps mindful of the disastrous crusader advance into Asia Minor in the winter of 1147–8, Frederick, choosing Adrianople as his headquarters, proceeded to occupy Thrace. At the same time, he made contact with provincial rebels in the Balkans and appeared to contemplate an assault on Constantinople. Both the occupation of Thrace and an attack on the Greek capital had been policies proposed to Louis VII in 1147. In mid-November, Frederick wrote to his son and regent, Henry VI, requesting he raise a war fleet from Italian ports to meet the German army in mid-March for an attack on Constantinople. At the same time, signalling that his ultimate goal had not changed, he asked Henry to arrange with his officials and the Venetian banker Bernard the German the transfer
