To solve this, we would have first looked for common letters, the most common letters in English are ETAIN.
We would also try and recognise letters by word length and word pattern, e.g. single letter words are probably A or I, double letters are likely to be things like L, P, O and so on.
Some trial and error should bear fruit.
