Source C is an extract from an interview with a teacher, which took place quite a long time after the war. Because the interviewee actually witnessed events take place first hand the source becomes more valid. The source appears to be unbiased as there would be no motive for doing so. A disadvantage to this source is that the teacher would be quite old at the time of the interview and with so much time passing between the occasions the accuracy of the statement could be brought to question.
As to which of the two sources is more useful, I would argue that source B is, it shows children looking happy, and I know that, although leaving their parents a large majority of evacuees were in fact quite excited about leaving for the countryside having spent most there lives in working class London.
2. Source G, is an extract from the novel “Carrie’s war”, despite being a fictional work, it highlights one of the main problems with the organisation of the evacuation, the mixing of different social classes between evacuees and hosts. I know that when people were evacuated there was no option as to where you stayed or whom you accepted, and because of this many people were given unsuitable placements. Some evacuees had never seen an indoor toilet before for example. However because it is only a novel it is not fully reliable evidence.
3. Some people, who believe evacuation was a success would say that because it moved children and other vulnerable groups such as pregnant women and important skilled workers such as teachers away from danger areas suspected of being bombed. In the First world war there had been bombing upon civilian targets, as well as more recently in the Spanish civil war, so the public feared such raids would take place in Britain too, and if nothing else evacuation put minds too rest.
Those who would say that evacuation was not a success could argue that it was poorly organised and made life miserable for both evacuees and hosts, but one could argue that both richer and poorer classes of society got a taste of what life was like for one another, the sources generally point towards evacuation being a good experience however source I shows that some people disagreed with evacuation.
Evacuation saved peoples lives and helped the country through difficult times, and besides it was not compulsory so if anyone disagreed with it then there children were not evacuated.
