As these historic photos show, the early months of the war meant residents had to quickly train as soldiers before departing for Europe and leaving their loved ones behind.
In our gallery you will also see young evacuees leaving the city and residents of Goodwood Road about to embark on an outing not realising that in two months time the country would be at war. You will also see some of the first areas to be hit by the air raids and the devastation of those bombs.

Ruination at Portsmouth Harbour Station. Taken from Southern Way-Wartime Southern here we see a burnt out carriage at the Portsmouth Harbour Station after a raid on August 12, 1940. The roof supports have been painted black and white for better sightseeing in the blackout. In this raid four trains were destroyed and the Isle of Wight landing stage was gutted. One man was killed.
