The naval battle can be checked against several British files as well as German and American archival records, but many diplomatic exchanges survive through personal accounts several steps removed from the speakers. Eugen Millington-Drake's compilation is especially useful because he participated in the events and assembled material from other witnesses. That proximity gives the work authenticity but also introduces the possibility of personal bias. The account warrants considerable weight with that qualification rather than treating participation as automatic proof. Reconstructing the diplomacy requires balancing archival breadth, proximity, authorship, and source criticism.
