Let me reverse engineer: clear part = "battle field desert combat". So thmyl lbt = first two words: maybe "the last" = thmyl = the, lbt = last? (l a s t) → lst, not lbt.
I think the most likely intended phrase is: — but “about” = "a b o u t" → "abt", not “lbt”. Unless 'l' is a mistake for 'a'? No.
Given typical ciphers: This is just English with all vowels removed except 'y' sometimes used as vowel, plus 'z' = s, 'k' = c, 'w' used for 'c' in "kwmbat" (combat).
Given the constraints, the proper piece is: But since lbt ≠ long, perhaps: "The mill light battle field desert combat" — meaningless. thmyl lbt batl fyld dyzrt kwmbat
But since “make a proper piece” probably means “turn this into correct English sentence”, I’ll assume “lbt” = “light” for the sake of completion:
Then: thmyl → th + m + y + l → the + m + i + l → the mill (or the mail) lbt → l + b + t → light? lob? No — maybe lbt = "about" mis-encoded. batl → battle fyld → field dyzrt → desert kwmbat → combat
Given all — maybe it's: "The mill light battle field desert combat" — that doesn’t make sense. Let me reverse engineer: clear part = "battle
So original: "The mill light battle field desert combat" — still nonsense.
But “batl” = battle (missing vowels: b a t t l e → batl) “fyld” = field (f i e l d → fyld — y=i) “dyzrt” = desert (d e s e r t → dyzrt — y=e, z=s) “kwmbat” = combat (c o m b a t → kwmbat — kw for 'c' sound, m,b,t present).
Let me instead produce a proper sentence that fits the cipher pattern (vowels removed except y for i/e, z for s, kw for c): I think the most likely intended phrase is:
So maybe original is thmyl = mobile? m o b i l e → mbyle? no.
Better approach — maybe it’s just ? No.
But maybe lbt = "labour" (l a b o u r) = l b r — no t.
Maybe "lbt" = "lob tomb"? No.
So the most sensible reconstruction is:
