Pompey was the pug dog of William The Silent. According to legend, during a campaign against the Spanish by Prince of Orange, William The Silent, his Pug, Pompey, thwarted an assassination attempt. One night at Hermigny, France, while the prince slept, assassins crept toward his tent. Pompey heard them and began barking and scratching to warn his master, finally jumping on his master's face to alert him to the impending danger.
The dog referred to in this legend may have instead been a Kooikerhondje. The dog carved in the monument at Delft does not have a flat face and was in 1873 referred to as a "spaniel" by a U.S. court.
