However, for a short time he made a huge impression on the students at Coburg High School.
Coburg High School's magazine, announces the appointment of Brigadier-General McNicoll, Scribe, vol 4, no. 1, May 1919
In the school's centenary history Loyal in All (available from the Coburg High School Historical Group), we are told that 'Brigadier General McNicoll, headmaster in 1920, was a distinguished former soldier with a 'romantic limp'. He rode a motorcycle with sidecar and was able to 'transform a boisterous junior cadet corps found misbehaving in the school yard. “Without raising his voice, within 10 minutes he had us drilling with the discipline and precision of Grenadier Guards", recalled a student of the day.' (Loyal in All, p.21)
Excerpt from Echoes, Coburg High School Magazine, 1986
At the end of 1920, McNicoll left Coburg High to take up the position of Principal of Goulburn Girls School (Presybterian Ladies College), in New South Wales.
