Brazil competed at the modern Olympic Games for the first time at the 1920 Summer Olympics in Antwerp, Belgium. 19 competitors, all men, took part in 10 events in 5 sports.[2]
Brazil won its first ever Olympic medals in Antwerp. All the three medals came in Shooting events. The five shooters had great difficulty getting to the Antwerp. First, the shooters boarded the Curvello steamship with the rest of the Brazilian delegation, but they had to go down in Portugal when they learned that the ship would not arrive in time for the competition. Then they took a train from Lisbon to Paris, and much of the trip was in an open car, with the athletes being exposed to rain and sun. In Paris, they changed trains, heading for Belgium. But in Brussels, where they expected the connection to Antwerp, some of the weapons and ammunition had been stolen. The athletes had 200 caliber 8 bullets, although they needed at least 75 for each. They made friends with the American athletes Alfred Lane and Raymond Bracken, who gave the Brazilians 2,000 cartridges and 50 targets.
