I haven’t read ‘Journey’s End’ but judging from Kevin Wilson’s other two books in his Bomber Command trilogy, ‘Men of Air’ and ‘Bomber Boys’, it is probably pretty good; I personally find his books most interesting for the first-hand accounts of the aircrew themselves (and slightly less balanced when it comes to judging the Bomber Command campaigns as a whole).

‘Journey’s End’ does however cover the final phase of Bomber Command’s war when many of its operations were carried out in daylight, in conditions of almost total air-supremacy and when the German defences had been rolled-back from the Atlantic coast by the advancing Allied armies; very different conditions from 1943 and early 1944. It also covers the period when target priorities had switched markedly (and rightly) toward the German oil infrastructure (as the targets that you list in your post very effectively demonstrates); synthetic oil / oil refineries by their nature are big targets and are not generally found in centres of urban population and they make better targets for lower-level (daylight) bombing. Again, very different from the targets of 1943 and early 1944.
