It is not, indeed, till within this year that I have been thoroughly acquainted with that memorable history of the Three Seals.
The history is this.

In the year 1760 the allies were in the course of operations against the son of the Mogul, now the present Mogul, who, as I have already stated, had made an irruption into the kingdom of Bahar, in order to reduce the lower provinces to his obedience.

The parties opposing him were the Nabob of Bengal and the Company's troops under Major Calliaud.

It was whilst they faced the common enemy as one body, this negotiation for the destruction of the Nabob of Bengal by his faithful allies of the Company was going on with diligence.

At that time the Nabob's son, Meeran, a youth in the flower of his age, bold, vigorous, active, full of the politics in which those who are versed in usurpation are never wanting, commanded the army under his father, but was in reality the efficient person in all things.
About the 15th of April, 1760, as I have it from Major Calliaud's letter of that date, the Nabob came into his tent, and, with looks of the utmost embarrassment, big with some design which swelled his bosom, something that was too large and burdensome to conceal, and yet too critical to be told, appeared to be in a state of great distraction.
