The Lombard League
The Lombard League was formed in 1167, largely out of the Veronese League
[3]. It was a Union of Lombard cities promising each other unity, against the
Emperor Frederick I Barbarossa. The
Lombard cities swore the oath at
Pontida, a small
Lombard village.

''The Oath of Pontida'' painted by Amos Cassioli.
After the disastrous defeat of
Pope Alexander III at the
Battle of Monte Porzio in May 1167 against
Imperial forces, only the Lombard League remained as the last legitimate fighting force opposing the
Emperor and was therefore heavily backed by the Pope.
Kenneth Pennington wrote: ''"Alexander’s inability to control Rome and the Papal States was due to his conflict with Frederick. Although he attempted to support the cities of Lombardy, he had neither the power nor the resources to render effective assistance."''
Frederick's 5th Italian Campaign
In September 1174, Frederick embarked on his 5th
Italian Campaign, to quench the constant revolts in
Lombardy and his quarrels with
Alexander III. Frederick led a force of 8,000
Knights [4] over the
Alps and arrived in
Piedmont in late September. His cousin
Henry the Lion and his forces, were once again not a part of the
Imperial campaign. Frederick wanted to take revenge on
Susa, for its "evil" behaviour of 1168, and on the 30 September his forces captured and burned down the town. His next aim was the town of
Asti, which he captured after a seven day siege. In October, Frederick finally received the promised
Imperial reinforcements from
Bohemia. Upon Frederick's rapid and fierce initial success,
Margraviate William of Montferrat and the Count of
Biandrate, abandoned the
Lombard League [5].
Siege of Alessandria
The siege of Alessandria was an important event in Frederick's 5th Campaign as this was a campaign of revenge, with the aim of the total destruction of the
Lombard League and the removal of the Pope
Alexander III. Frederick's next goal was therefore the Lombard city of
Alessandria.
Alessandria was founded by
Milanese refugees, who fled after Frederick's forces burned and destroyed the
Milan in 1162
[6] and named after
Pope Alexander III. The siege of the "Straw City", called so because all the roofs were covered with straw, began at the end of October. To Frederick's surprise and anger,
Alessandria population proved to be robust and determined and his forces were not able to take the city so he had to spend the winter in front of its gates. On
Holy Saturday, Fredericks forces managed to enter the city by digging tunnels under its walls, but the attack was repulsed by the
Milanese with heavy losses
[5].
Alessandria withstood, and that was the first victory of the
Lombard League. Frederick had to break off the siege due to an advancing
Lombard army and retreated to
Pavia [5].
Treaty of Montebello
On the 16. of April 1175, Frederick and the
Lombard League negotiated peace at the Castle of
Montebello but after long talks, negotiations broke with no result
[4]. Frederick knew that a battle is imminent and traveled to
Chiavenna to meet
Henry the Lion.
Henry the Lion however refused to help his cousin as he thought that a Frederick's defeat will allow him to obtain greater power
[5].
The Battle
After Frederick's setback at
Alessandria, the failed agreement of
Montebello and the refusal of his cousin
Henry the Lion to help him, Frederick finally received some good news and reinforcements from
Germany [1]. The
German reinforcements crossed Lukmanier Pass into the
Lake Como region in April 1176. Frederick I Barbarossa, Philipp I of Heinsberg
[12] and Archbishop Wichmann of
Magdeburg [13] rode secretly from
Pavia along the
Ticino River, to meet the reinforcements and to lead them to a joint operation with his main forces. Frederick received 1,000
Knights and 1,000 foot soldiers from 16 different
German rulers
[14]. At
Como,
Lombard imperialist allies increased the reinforcements to about 3,000
[1]. The
Imperial army was largely a cavalry force of
German Knights.
The
Milanese were informed about Frederick's plan and prepared for battle. A
Carroccio, or a sacred war wagon drawn by
oxen, was build and under their battle traditions, it was decorated with the city standard and an altar upon which the cross of
Archbishop Aribert of Milan was erected. In 1038,
Archbishop Aribert led the victorious defence of
Milan against the
Holy Roman Emperor Conrad II, and therefore his cross was a symbol of victory against the
Empire. According to Sire Raoul, an historian from
Milan, 900
Knights came from
Milan and around 550
Knights from three other towns, the rest of the
League's forces were foot soldiers. The "Company of Death" was a foot soldier unit, that according to
Milanese chronicles was led by
Alberto da Giussano, and formed the core of the
Lombard infantry.

Skirmish at the Carroccio
While Frederick and his reinforcements were on their way back to
Pavia to join the main
Imperial force, the
Lombard League placed about 3,500 men near the west bank of the
Olona. The infantry with the
Milanese war cart, the
carroccio, stood in a hastily fortified position at Borsano. The
Lombards knew that Frederick was about to skirt through their area, however, the
Lombards did not know how close Frederick already was. At dawn on the 29 May, the
Lombards sent a reconnaissance unit of 700
horsemen to the Seprio
landscape. At the same time, the
Emperor had crossed the
Olona and was marching south from
Cairate, five miles northeast of
Busto Arsizio.
Here, the battle commenced. The
Lombard reconnaissance and the 300
Imperial vanguard clashed. The clash was brief and bloody and with Frederick already on the
horizon, the
Lombard reconnaissance broke off and fled beyond Borsano.
Now, Frederick and his
Imperial German army launched a rampant and brutal attack on the
Lombard forces near Borsano -
Legnano. The
Lombard cavalry was largely routed but managed to escape the
skirmish, leaving the infantry and
Carroccio on its own. Frederick advanced to the
Carroccio, and assaulted the infantry, largely made up of
Farmers and the Company of Death and in total the largest contingent of the
League.
M.B. Synge wrote this about the Company of Death: ''" Nine hundred desperate patriots forming the Company of Death defended the sacred car. Seeing the Germans were gaining ground, fearful for the safety of their treasure, they suddenly knelt down and renewed their vow to God that they would perish for their country. "''
[16]
The infantry positioned itself in a
phalanx-like line and fought with great
determination. The Fight around the
Carroccio was a long and bloody fight in which the
Lombard infantry brought the
Imperial army to a
stalemate. Despite the difficulties the
Imperial cavalry had against the
Lombard infantry, it would have still prevailed in the long run. Finally, the
Lombards received help from its regrouped cavalry and from a
Brescian cavalry that was called to aid by the fleeing reconnaissance troops
[1]. The regrouped reconnaissance troops and the
Brescian cavalry jointly attacked Frederick's army from the rear.
The decisive assault was made by the
Brescians, who managed to break through the lines and attack Frederick directly. In this attack, his guards and
standard-bearer were killed, and Frederick was thrown off his horse and believed to be dead. Upon this, the
Imperial troops panicked and fled, pursued to the
Ticino by the
Leagues cavalry. The generals tried to rally the men in vain.
[18]. The
booty and prisoners of war taken by the League were immense
[1].
Aftermath

Lombard Knights looking for Frederick's dead body
After the battle, Frederick's rule over
Lombardy was decisively broken.
The
knights that managed to escape, gathered in
Pavia. There, they brought the news of Frederick's presumed death to his wife
Beatrice I Countess of Burgundy.
Beatrice and the
Empire mourned
Frederick's demise but after several days the Emperor appeared at the gates of
Pavia.
H. E. Marshall wrote: ''" Then, greatly to the joy of all, after three days Barbarossa suddenly appeared before the gates of Pavia. Although wounded and bruised and left for dead Frederick had not been killed. "''
[18]
The victories of the
Lombard League, forced Frederick to travel to
Venice. In the
Peace of Venice, 1177, Frederick and
Alexander III reconciled. The
Emperor acknowledged the
Pope's sovereignty over the
Papal States, and in return
Alexander acknowledged the
Emperor's overlordship of the Imperial Church. The
Peace of Venice were heavily instigated by Archbishop Wichmann of
Magdeburg, who was amongst the defeated at
Legnano.
The
Lombard cities, however, continued to fight until 1183, when, in the Peace of Constance, Frederick conceded their right to freely elect town magistrates. The Treaty was cast in
Bronze.
Frederick did not forgive
Henry the Lion for refusing to come to his aid in 1176. Taking advantage of the hostility of other German princes to Henry, Frederick had Henry tried in absentia by a court of bishops and princes in 1180, declared that Imperial law overruled traditional German law, and had Henry stripped of his lands and declared an outlaw.
On the 27th of January 1186, Frederick's son
Henry VI married
Constance of Sicily in
Milan as a sign that peace had really been established.
Actual battlefield
The battle is traditionally tied to the name of
Legnano, since the League's forces came from that town. Actually, as local historians have ascertained, the battle was fought a couple miles west of Legnano, where today
Villa Cortese and Borsano,
frazione of
Busto Arsizio, stand.
