 The club 's second stint in the Southern League was interrupted by the outbreak of the Second World War in 1939 , which saw newly appointed manager Archie Clark and most of the players assigned to work at the local dockyards . When competitive football resumed , Gillingham played in the first incarnation of the Kent League , winning the title in both 1944 – 45 and 1945 – 46 . In the second of these seasons the team also won the Kent Senior Cup , Kent County Challenge Cup and Kent League Cup , to complete a clean sweep of every senior trophy in the county . Following their Kent League triumphs , the Gills returned to the Southern League for the 1946 – 47 season , in which the team again won two trophies , claiming both the Southern League Cup and the Southern League title itself , and registered a club record 12 – 1 victory over Gloucester City . Striker Hughie Russell scored nine goals in the match , and missed out on double figures when he hit the bar late in the game .
