Goedendag

A goedendag (Dutch for "good day"; also rendered godendac, godendard, godendart, and sometimes conflated with the related plançon) was a weapon originally used by the militias of Medieval Flanders in the 14th century, notably during the Franco-Flemish War.

[1] The weapon was used to great effect by the guildsmen of Flanders' wealthy cities against the French knights at the Battle of the Golden Spurs near Kortrijk (Courtrai) on 11 July 1302.

The thicker knob under the spike, a safeguard against the horse impaling itself and then going on to crash into the defender, served the same purpose as the cross bar on a boar-spear.

[5] Verbruggen describes the role of the goedendag thus: "They were placed between the pikemen, or in the second rank, so that with their shorter, very heavy weapons they could put the horses out of action.

In contrast with the goedendag, these were expressly built for professional warriors, to rip a rider off his horse while he was charging or passing by.
