During the Revolt of 1857, who wrote to the 48th Native Infantry that, "they had acted for the faith and awaited the 48th's orders".

7th Awadh Irregular Cavalry

The correct answer is Option (1) → 7th Awadh Irregular Cavalry

" The reason for the similarity in the pattern of the revolt in different places lay partly in its planning and coordination. It is clear that there was communication between the sepoy lines of various cantonments. After the 7th Awadh Irregular Cavalry had refused to accept the new cartridges in early May, they wrote to the 48th Native Infantry that “they had acted for the faith and awaited the 48th’s orders”. Sepoys or their emissaries moved from one station to another. People were thus planning and talking about the rebellion",.
