What does "In order that I may situate myself in this narrative," mean? Thank you!
CONTEXT:
Mr Buller at the Admiralty informs me that you are desirous of knowing something of the sea career of James Dyer whom I understand to have been your particular friend. Knowing that I sailed upon the Aquilorx as Chaplain throughout much of the '50s, Mr Buller suggests I might furnish you with some recollections which — craving your indulgence for the distortions of memory occasioned by the passing of some twenty years — I shall now endeavour to do.
In order that I may situate myself in this narrative, let me say only that I came aboard the Aquilon in the spring of '53 having finished at the University.
﹉What does "In order that I may situate myself in this narrative," mean? Could you paraphrase or explain it for me? Waiting for your help, thank you!
