- 10 nations (Belgium, Chile, Denmark, France, Germany, Great Britain, Norway, Russia, Sweden, USA)
- 62 riders / 70 horses
- 88 entries (40 in Jumping; 21 in Dressage; 27 in Eventing)
- The two days of equestrian sport in the Olympic Stadium (16 July 1912 - Jumping of Eventing and Individual Jumping; 17 July 1912 - Dressage of Eventing and Team Jumping) attracted 17,250 and 9,881 spectators respectively
- It took two years – 1910 and 1911 - to construct the new brick-built Olympic Stadium, which, 44 years and 78 years later, served for the 1956 Olympic Equestrian Games and the 1990 FEI World Equestrian Games respectively.
- Sweden and Germany fielded full teams in all disciplines. Six other countries – Belgium, Denmark, France, Great Britain, Norway and the USA – sent a limited number of riders and horses, who were often used in two or even all three disciplines. Russia had a six-man jumping team and one dressage rider, while Chile delegated two officers who were at that time at the German cavalry school in Hannover.
Jumping (40 riders from eight nations)
Dressage (21 riders from eight nations)
Eventing (27 riders from seven nations)
There were separate competitions for the individual and team medals, although both were over the same course of 15 obstacles, four of which had to be jumped twice. There were 29 jumping efforts. The maximum height was 1.40m, maximum width 4.00m, and speed 400 m/min.
Six riders per country were allowed in the individual competition.
The 1912 Dressage test did not contain piaffe and passage, but five jumps up to 1.10m. At the end of the programme the horses had to jump a painted cylinder rolling towards them. There were bonus points to be won when the rider held the reins in one hand.
Only 10 years after a Championnat du Cheval d’Armes was held for the first time in France, the Olympic “Military” was organised in Stockholm. Only teams of three or four riders were allowed and they had to be officers on their own horses belonging to their army. The competition was held over five days (with one rest day), as follow:
1st day: A: Endurance ride over 55km in 4 hours
B:Cross-country over 5 km in 15 minutes (12 obstacles)
3rd day: C: Steeplechase over 3500m. in 5 minutes and 50 seconds (10 obstacles)
4th day: D: Jumping over 15 obstacles, up to 1.30m high and 3.00m wide
5th day: E: Dressage
In each of the five phases a maximum of 10 points could be won.
Sweden took the team gold medal ahead of Germany and the United States. Member of the latter was Capt. Guy Henry on Chiswell. In the early thirties General Henry was chief of the US Cavalry and, during the 1932 Olympic Games, president of the FEI.
