The motto of Haarlem is "Vicit vim virtus" (Latin for virtue conquered violence). The barren branches refer to the burned trees in the Haarlemmerhout, which were burned again and again during various sieges, most notably during the siege by the army of Jacqueline, Countess of Hainaut in 1428. Haarlem had taken side with the Cods in the Hook and Cod wars, and thus against Jacoba of Bavaria. The bells refer to the damiaatjes. Two bells were given to the city of Haarlem's St. Bavochurch to commemorate the heroic cutting of the harbour chain during the Siege of Damietta (1218) with a "saw ship", a legendary ship equipped with an iron saw fastened along the bow and front keel. This ship sawed through the harbour chain and allowed the fleet to attack the city, which was a success.
