Was there any last attempt of reconciliation before the Battle of Bunker Hill?

Yes, before the Battle of Bunker Hill, there were efforts at reconciliation between the American colonies and Britain. The most notable was the Olive Branch Petition, sent by the Second Continental Congress in July 1775, which sought to address grievances and affirm loyalty to the British crown. However, King George III rejected the petition and declared the colonies in rebellion, leading to further escalation and ultimately the battle in June 1775.
