Prior to the start of the General Assembly session on August 9th, both supporters and opponents had lobbied members of the Tennessee Senate and House of Representatives. Though the Democratic governor of Tennessee, Albert H. Roberts, supported ratification, most lawmakers were still undecided. Anti-suffragists targeted members, meeting their trains as they arrived in Nashville to make their case. When the General Assembly convened on August 9th, both supporters and opponents set up stations outside of chambers, handing out yellow roses to suffrage supporters and red roses to the "Antis."  As the House prepared to take up the issue of ratification on August 18, lobbying intensified.  The vote on the resolution would be close. Representative Harry Burn, a Republican, had voted to table the resolution both times. When the vote was held again, Burn voted yes. The 24-year-old said he supported women's suffrage as a "moral right," but had voted against it because he believed his constituents opposed it.  The same day ratification passed in the General Assembly, Speaker Walker filed a motion to reconsider. When it became clear he did not have enough votes to carry the motion, representatives opposing suffrage boarded a train, fleeing Nashville for Decatur, Alabama to block the House from taking action on the reconsideration motion by preventing a quorum. Thirty-seven legislators fled to Decatur, issuing a statement that ratifying the amendment would violate their oath to defend the state constitution. The ploy failed. Speaker Walker was unable to muster any additional votes in the allotted time. When the House reconvened to take the final procedural steps that would reaffirm ratification, Tennessee suffragists seized an opportunity to taunt the missing Anti delegates by sitting at their empty desks. When ratification was finally confirmed, a suffragist on the floor of the House rang a miniature Liberty Bell.

On August 18, 1920, Tennessee narrowly approved the Nineteenth Amendment, with 50 of 99 members of the Tennessee House of Representatives voting yes. This provided the final ratification necessary to add the amendment to the Constitution, making the United States the twenty-seventh country in the world to give women the right to vote.  Upon signing the ratification certificate, the Governor of Tennessee sent it by registered mail to the U.S. Secretary of State Bainbridge Colby, whose office received it at 4:00 a.m. on August 26, 1920. Once certified as correct, Colby signed the Proclamation of the Women's Suffrage Amendment to the U.S. Constitution in the presence of his secretary only.
