When the war ended on 11 November 1918, Long was forced to put the education scheme into full effect earlier than expected. He was promoted to colonel and then temporary brigadier general on 1 January 1919. In March, with the scheme fully underway, Long's health began to suffer, and in April he handed over control to Brigadier General Walter McNicoll. For his services, Long was awarded honorary Doctor of Letters (LLD) degrees by both the University of Cambridge and the University of Manchester, and was appointed a Commander of the Order of the British Empire (CBE).
