Man O War lost his only race on that date. A series of mishaps caused his demise, from the illness of Mars Cassidy the regular starter to Charlie Pettingall`s very poor start, He had been a finish line judge for years and had not started a race in a long time. MOW collided with 2 horses right after the start (the view of the collision was blocked by trees)so it is not in the results charts. Those tree were removed after 1919 season so as not to block the chart caller`s view again. MOW was taken back a second time and lost many lengths in that collision. The loss made MOW the most famous horse in history. His next start drew 35,000 people to Spa when its best crowd had been 5 to 10 thousand before that.
