Which game caused people's death because they used cannonballs as balls?

Boules is a collective name for a wide range of games similar to bowls and bocce in which the objective is to throw or roll heavy balls (called boules in France, and bocce in Italy) as close as possible to a small target ball, called the jack in English.

Boules-type games are traditional and popular in many European countries and are also popular in some former French colonies in Africa and Asia.

Boules games are often played in open spaces (town squares and parks) in villages and towns. Dedicated playing areas for boules-type games are typically large, level, rectangular courts made of flattened earth, gravel, or crushed stone, enclosed in wooden rails or backboards.

For centuries, people have been playing games that require tossing balls. Danger, however, became part of the game at times. In Marseille in 1792, a game of boules left 38 dead, when a group of soldiers played a game using cannonballs as boules at a convent where kegs of gunpowder were being stored.

In Provençe, during the 18th century, variations of boules became very popular: longue, butaban, and roulette. Longue eventually overshadowed the other two games, becoming the dominant game in the early 19th century. The boules were made of boxwood, sheathed in nails.

However, the boules were dangerous, and often bystanders complained of injuries. The game was forbidden to be played in public areas, but boules continued at cafés and in private gardens.
