Final answer:
The actions of the Englishman upon entering an oasis where everyone surrenders their weapons cannot be determined without additional context or specific reference to the narrative source.
Step-by-step explanation:
The query about the Englishman’s actions upon entering an oasis, where everyone must surrender their weapons, derives from a narrative context likely fictional or literary in nature rather than a historical account.
The query does not provide enough specific information to reliably identify the text from which it is taken, thus making it impossible to give an accurate answer to what the Englishman does in that situation. Without the relevant text or additional details, the character's actions cannot be ascertained.
