"We shall not see him again" change into Past simple.
If you change only the verb in this sentence to simple past, it won't make any sense. This is how it would read: We saw him not again.
We did not see him again
I san,look
To change the sentence "We shall not see him again" into the simple past tense, you need to use the past tense form of the verb "shall" and the simple past tense of the verb "see".
In the simple past tense, the verb "shall" is changed to "should" when used in the first person plural form. The verb "see" is changed to "saw" in the simple past tense.
Using these changes, the sentence "We shall not see him again" becomes "We should not saw him again" in the past simple tense.
However, it's important to note that "should not saw" is not grammatically correct in English. Instead, you can rephrase it to say "We were not able to see him again" or "We could not see him again" in the past simple tense.
