>The trouble with Koshala[kingdom] seems to have arisen over a piece of land in the vicinity of Varanasi. It had passed to Bimbisara[king of Magadha] as the dowry of his Koshalan bride. When she died of grief over Bimbisara’s death, Prasenajit[king] of Koshala, her father, revoked the grant of this land and resumed control of it. Ajatashatru[son of Bimbisara] endeavoured to retake it but seems at first to have been defeated. His claim to the disputed enclave was, however, enhanced when the aged Prasenajit, falling prey to the usurpation of his own son, headed for Magadha as a supplicant. Alone but for a devoted servant, the old king reached the walls of Rajagriha and there, while waiting overnight for the gates to open, died of exhaustion and exposure. Despite their past differences, Ajatashatru of Magadha promptly honoured the memory of this Indian Lear and vowed to avenge his treatment by the Koshalans. But he bided his time, first dealing with another major threat to his kingdom and then benefiting from the chance annihilation of the Koshalan army; encamped in the dry bed of the river Rapti, it had been suddenly over-whelmed by a flash flood. Thereafter, although the sources are silent on the details, Ajatashatru seems to have overrun Koshala, which promptly disappears from the record.

Lincoln was already pressured out of the idea before the war even ended. By the time Booth killed him he had already given up on the idea, from what I've heard. He definitely did want to do it though, he just didn't have the means to make it happen. I don't know if it was southern or northern politicians that argued against sending them back.
