Did Lagarde Save AIG?

Ambrose Evans-Pritchard claims that it was Christine Lagarde who beseeched Henry Paulson to save AIG in order to bail out European banks that would otherwise have gone down:

We now know that it was French finance minister Christine Lagarde who begged Mr Paulson to save the US insurer AIG last week. AIG had written $300 billion in credit protection for European banks, admitting that it was for "regulatory capital relief rather than risk mitigation". In other words, it was underpinning a disguised extension of credit leverage. Its collapse would have set off a lending crunch across Europe as banking capital sank below water level.
