77% of the mothers and children of Scotland who were evacuated by the government scheme in September 1939 were back home by January 1940, that is 129,046 out of 167,243.
There were other attempts by the government to organise evacuation, but they were unsuccessful and involved small numbers of children.
Most parents' natural reluctance to be separated from their children was strengthened by stories of the unhappy experiences of the first evacuees and of course there was no bombing of the British mainland until 1940 and none in Scotland until 1941.
The war was very frightening and people's lives were already disrupted by it. It seemed better that families should stick together.
