Study Sources A and B in the Sources Booklet - Edexcel - GCSE History - Question 2 - 2021 - Paper 1

Source A provides valuable information regarding the methods and circumstances under which blood transfusions were carried out during the war. It highlights the firsthand experience of Charlie Shepherd, who shares details on when and how blood transfusions were utilized, thus providing context about their success and limitations. His statement that he was actively involved in the process offers insights into the practical application, supporting the idea that blood transfusions were becoming more common during the conflict. However, Source A mainly reflects Shepherd’s subjective experience and might not encompass broader statistical or factual data.

On the other hand, Source B emphasizes the advancements made in blood transfusion techniques and outlines the surgeon's professional role in improving the methods used. It illustrates the evolving understanding of blood transfusions and acknowledges challenges faced earlier on, such as the risk of loss from severe injuries. This source is beneficial as it evaluates the broader implications of blood transfusions as a treatment option, potentially drawing upon more systemic experiences from other practitioners in the field.

Both sources are thus useful for understanding the multi-faceted context of blood transfusions on the Western Front, with Source A providing a personal narrative and Source B furnishing a more general overview, yet both exhibit limitations regarding their scope.
