Until ((they) were) dead

[Sped Tiger]

Which one of the sentences I've written is correct?
a. All of those soldiers were tortured until dead;
b. All of those soldiers were tortured until were dead;
c. All of those soldiers were tortured until they were dead.

 

[Barque]

Sentences a and c are grammatical but not very natural.

Sentence b isn't grammatical.

I'd expect "All [of] those soldiers were tortured to death/till they died".

 

[SoothingDave]

"Tortured to death" would be most natural.

 

[Sped Tiger]

Sentences a and c are grammatical but not very natural.

Sentence b isn't grammatical.

I'd expect "All [of] those soldiers were tortured to death/till they died".

Why are those grammatical, but b isn't?

 

[emsr2d2]

b. All of those soldiers were tortured until they were dead.

Why are those grammatical, but b isn't?

Sentence b wasn't grammatical because you omitted the pronoun "they" (and failed to end the sentence with a full stop).

Sentence b wasn't grammatical because you omitted the pronoun "they" (and failed to end the sentence with a full stop).

Is it natural to say “Sentence b isn’t grammatical….”? If “is” is correct, are “wasn’t and “isn’t optional?

@Winwin2011 Sentence (b) isn't grammatical.
