Those who ignore history are doomed to repeat it but those who write alternative history can change it.
But to change history at a particular point in time (or, more properly, write an alternative history novel set during that period) one must understand the events that took place at that time. One must also understand the technology of that time.
For these reasons, I am presenting non-fictional information one would need to write a fictional story.
Note: The commonly used expression, “Those who ignore history are bound (or doomed) to repeat it,” is actually a mis-quotation of the original text written by George Santayana, who, in his Reason in Common Sense, The Life of Reason, Vol.1, wrote “Those who cannot remember the past are condemned to repeat it.”
