The Company of Death is the name used in the historical literature of English language for two related chosen tactical corps, two selected bands of warriors, entrusted to guarantee the cohesiveness and efficiency in battle of both the Milanese and Lombard League's militias through their bound by oath to the defence of the Milanese Carroccio, the wagon on which the standard of the Lombard allies stood.
They fought in the Battle of Legnano (29 May 1176) against the imperial army of Frederick I Barbarossa Emperor of the Holy Roman Empire, in his 5th Italian Campaign, and were determinant in his decisive defeat.
The two corps who formed the Company of Death were the Company of the Carroccio, an infantry unit of 300 men, and the real and effective Company of Death, a cavalry unit of 900 men, commanded according to tradition by Alberto da Giussano.
Saputo dell' arrivo dell'imperatore, i Milanesi ordinarono di preparare le armi per poter resistere. E viene fatta una società di novecento uomini eletti che combattevano su grandi cavalli i quali giurano che nessuno sarebbe fuggito dal campo di battaglia per paura della morte e non avrebbero permesso che nessuno tradisse il comune di Milano; e inoltre giurarono che sarebbero scesi in campo a combattere contro l'imperatore ogni giorno. A quel punto la comunità scelse le armi e il vessillo e ad ognuno venne dato un anello in mano; e vennero reclutati come cavalieri al soldo del comune così che, se qualcuno fosse fuggito, sarebbe stato ucciso. Capo di questa società era Alberto da Giussano che aveva il vessillo del comune. Poi venne fatta un'altra società di fanti scelti per la custodia del carroccio, i quali tutti giurarono di preferire morire che fuggire dal campo di battaglia. E vengono fatte trecento navi a forma di triangolo e sotto ad ognuna c'erano sei cavalli coperti, così da non essere visti, che trascinavano le navi. In ogni nave vi erano dieci uomini che muovevano falci per tagliare l'erba dei prati come i marinai muovono i remi: era una costruzione terribile contro i nemici.
(Galvano Fiamma, Chronica Galvanica cap. 291 f. 81v).
Informed of the Emperor's coming, the Milanese (authorities) commanded to prepare the weapons to resist him. And a company ("societas") is made of nine hundred chosen men, fighting on great horses, who swear that no one would have fled from the battlefield for fear of death and they would not allow anyone to betray the Municipality of Milan, and also they swore that they would have taken every day to the battlefield to fight against the Emperor. At that point, the Municipality chose the weapons and the banner, and a ring was given in hand to each one of these men and they were recruited as knights in the pay of the City, so that if anyone had fled he would rightly have been killed. Head of this company was Alberto da Giussano, who carried the banner of the City. Then came another company made of chosen soldiers on foot, for the custody of the Carroccio, and all of them swore they would rather die than flee from the battlefield. And three hundred battle wagons ("vessels") are manufactured and for each one there were six horses covered (by armour), dragging the vehicle. In every wagon there were ten men moving sickles to cut grass meadows, to cut hostiles as sailors move the oars: it was a terrible equipment against the enemies.
