Well I held onto Lahore but have no chance of continuing our attack as we are severely lacking in military power due to our units being old in comparison to Asoka and Hatty for that matter.
IBT: Artillery attack Lahore and we lose 4 units plus our fishing nets have been destroyed.
(1)-1780AD - Hmmm... How to hold Lahore! Asoka's artillery will take it back in no time. I ask for a cease fire but Asoka rejects it. He'll only take peace if we give him back Lahore. He's quite adamant about this as I tried every turn through to the end and he asks for Lahore every time.
I go offensive with our cannons and attack the artillery. Got 2 of them but lost 2 cannons.
IBT: - Lose another rifle... Almost no defenders left! All cannons

.
(2)-1785AD - Just moving lots of units around.
IBT: - Lose another rifle.
(3)-1790AD - Kill offending artillery but the cannon is stuck in enemy territory now.
IBT: Lose a cannon and a rifle.
(4)-1795AD - I move a force of cannons towards the next city. We have to do this now and get him quickly and hope that he'll then take peace. I think it's suicide as I don't have enough units but we are aiming for a ring and have to at least try.
IBT: Loose a rifle and a grenadier this time.
(5)-1800AD - Steam comes in and I go for Railroad to allow us to at least get some decent defenders to hold these cities.
MM has some huge stacks moving through our territories and going for Asoka. I ask him to take Karachi.
IBT: We lose 2 more defenders... Can we hold onto Lahore??
(6)-1802AD - How now?? I only have cannons as defenders. I pulled the force that was going towards the next town back to boost the defenses by at least a little bit. Cannons are not good defenders against cavalry and artillery.
Asoka hasn't changed his mind about peace. He wants gold too.
IBT: Now Mansa makes peace with Asoka!!!! We are screwed!
(7)-1804AD - Just moving units around again.
(8)-1806AD - Whip a rifle in Lahore and get a CGII rifle to the city finally. Maybe we can hold it for a couple more turns. Not much good against artillery though.
IBT: GK has decared on us!! F**K. Now is not the time arsehole.
(9)-1808AD - Classic, GK is attacking us with the power of his Keshiks.
(10)-1810AD - Well... didn't get anywhere in terms of expanding our ring on these turns. But at least for the moment we're holding Lahore and GK is not really a threat to us.
Here's the situation at Lahore.
Good luck!! We're going to need a bit here.
And the save:
