Final answer:
Without additional context, the duration of William's commitment to Sir Ector and the reasons his father sent him away are unclear. The references suggest themes of military conflict, family dynamics, and personal struggle.
Step-by-step explanation:
The question refers to a narrative that does not clearly define the length of "Williams commitment to Sir Ector." Based on the provided text references, it seems that William might be a character in a larger story, possibly set against a historical backdrop. His father sent him away potentially due to military, familial, or safety concerns, as suggested by the mentions of conflict, escape, and parental protectiveness in the excerpts.
It is not possible to ascertain an exact duration of William's commitment or the specific reasons for his father sending him away without more context or direct reference to those events in the story. The texts reference military engagements, familial bonds, and personal struggles, which alludes to a social or historical drama rather than a specific period of service to Sir Ector.
