<P> In 2009, a number of activities were proposed to commemorate the 250th anniversary of the Battle of the Plains of Abraham . A plan to hold a reenactment of the battle itself (as well as a reenactment of the subsequent French victory of 1760 at the Battle of Sainte - Foy) was cancelled due to threats of public disorder . Leaders of separatist parties described the event as a slap in the face for Quebecers of French ancestry and as an insult for the francophone majority . Some sovereigntist groups threatened or made indirect threats by stating that if the event took place, there could be violence . The movement against re-enactment and these threats of violence led the National Battlefields Commission to cancel the event . </P> <P> Another commemorative event was proposed for the anniversary, the Moulin à paroles . Thousands gathered on the Plains of Abraham to listen to recitations of 140 significant texts from Quebec history, including the 1970 FLQ Manifesto . The inclusion of that document in the event led to condemnations and a boycott from federalist politicians and the withdrawal of some government funding for the event . The Moulin à paroles took place without incident . </P> <P> During building within the Old city of Quebec, a cannonball was found which is believed to have been fired during the siege . </P>
