The Shahbandar.
But will he do it?
He will. If I can show him collateral.
I don't have enough collateral. Not in my own funds. Not even in the local treasuries.
But there must be enough silver in eighteen thousand tents to assemble five million rupees.
I will hold it, and give him a note of obligation using it as collateral. If we reach Ahmadnagar, I will squeeze the five million rupees many times over from every traitorous mansabdar I do not hang. I will confiscate their jagir estates and let them buy them back. I can easily confiscate enough to return the Shahbandar his loan, and then my men will have back their silver.
If we do not reach Ahmadnagar, it will be because we are dead. So what will it matter? We will make an oath to reach the city or die.
Only one problem remains.
How to move the coin from Surat to Burhanpur. Secretly. No one must know where it came from or that it's being transferred. But a train with fifty lakhs of rupees must be heavily guarded. And the guards will betray its value.
Unless there can be some other reason for a heavily guarded train from Surat to Burhanpur. A reason that would not automatically evoke suspicion. Possibly a person of importance. Someone whom all India knows cannot be touched. Someone important to the Moghul.
