From 1919 to 1923, Thành (Ho) began to show an interest in politics while living in France, being influenced by his friend and Socialist Party of France comrade Marcel Cachin. Thành claimed to have arrived in Paris from London in 1917, but the French police only had documents recording his arrival in June 1919.
The Romanian Army's 4th and 5th infantry divisions were moved to Bessarabia. In southern Bessarabia a territorial command unit formed by the Romanian Army's 15th Infantry Division was established. By the end of June tensions in the area had eased.
On 3 June, Romania was forced into further retreat but extended its line of defence along the Tisza River and reinforced its position with the 8th Division, which had been moving forward from Bukovina since 22 May.
In June 1919, the Allies declared that war would resume if the German government did not sign the treaty they had agreed to among themselves. The government headed by Philipp Scheidemann was unable to agree on a common position, and Scheidemann himself resigned rather than agree to sign the treaty.
John Hartfield left his home in Ellisville seeking a better life in East St. Louis. In 1919, he traveled back to Ellisville to visit his white girlfriend, Ruth Meeks, taking a job as a hotel porter in Laurel. When the relationship became known to some white men, they determined to kill Hartfield. They accused Hartfield of raping Meeks, who they claimed was 18, although she was actually in her mid-twenties. Hartfield managed to elude them for a while, but they pursued him for several weeks. Sheriff Allen Boutwell in Laurel raised donations to fund a hunting party with bloodhounds at the request of Sheriff Harbison. He was finally apprehended attempting to board a train on June 24, and was turned over to Sheriff Harbison, who placed him in the charge of a deputy and left town. The deputy immediately released him to a mob. Hartfield had been wounded, so a white doctor, A. J. Carter, treated his wounds to keep him alive long enough to be murdered. At 5:00 PM on June 26, 1919, a large cheering crowd assembled to watch the premeditated murder of John Hartfield.
