1970 Stanley Cup Finals

Game one

Three minutes and fifty-seven seconds into the second period of game one, a hard shot from Boston forward Fred Stanfield was deflected and struck St. Louis goaltender Jacques Plante in the forehead of his face mask, splitting the mask in half and knocking Plante unconscious.^[2] The first thing Plante said after he regained consciousness at the hospital was that the mask saved his life.^[3] Plante would not return for remainder of the series. Doctors later said if Plante hadn't been wearing a mask, he surely would have been killed. Ernie Wakely took over in goal but only held off the Bruins for a few minutes before becoming a rather easy mark for Bruins sharpshooters, with Johnny Bucyk recording a hat trick, and the Bruins winning the game by a score of 6–1.

Game two

In game two, Ed Westfall and Derek Sanderson each scored twice for the Bruins in a 6–2 victory for Boston.

Game three

In game three, Wayne Cashman scored twice, Phil Esposito recorded three assists, and Boston defeated St. Louis 4–1 to take a 3–0 lead in the series.

Game four

Bobby Orr scored the game-winning goal on Mother's Day in game four against goaltender Glenn Hall, with an assist from close friend and teammate Derek Sanderson, just forty seconds into overtime. The subsequent image of Orr flying through the air, his arms stretched out in victory — (he had been tripped by Blues' defenseman Noel Picard immediately after scoring the goal) — is considered the most famous and recognized hockey image of all time. With the win, the Bruins completed the sweep and became the first American team to win the Stanley Cup since the Chicago Black Hawks in 1961, and Orr was awarded the Conn Smythe Trophy as playoffs MVP.

Engraving notes

• Tom Johnson's name was engraved T. Johnson TR by mistake. Johnson was the assistant manager, not the trainer. The mistake was not corrected on the Replica Stanley Cup created in 1992–93.
• Coach, Manager, Asst. Manager and both trainers were listed after the players. Traditional Coach, Manager and Asst. Manager are listed before the players with the rest of the team executives.
• ^{^A} #6 Ted Green (D) received a head injury in a pre-season game. He missed the entire season, but his name was still engraved on the Stanley Cup. #31 John Adams (G) and #22 Ivan Boldirev (C) had their names engraved on the Cup before they played their first NHL game. Boldirev played his first NHL game for Boston during the 1970–71 season, Adams played his first NHL game for Boston during the 1972–73 season. Dan Schock played in the minors but was called up to play one playoff game, earning a spot on the Stanley Cup. Ron Murphy played only 20 regular-season games and had officially retired in March, but his name was engraved on the Cup.
• Boston Bruins did not have an official Captain – John Bucyk, Phil Esposito, Ed Westfall were Alternate Captains. Bucyk was presented with the Cup because he was the most senior letter-wearer (a scenario that would repeat in 1972).
• After Boston included 3 players who did not play for the team that season, the NHL only allowed players who dressed in the playoffs to be included on the Stanley Cup.
• The NHL feared that the Original Stanley Cup bowl was becoming too brittle. So a new Presentation Stanley Cup was made and first awarded in 1970. It was identical to the original bowl. The Original bowl was retired and put on permanent display at the Hockey Hall Fame.
