Bengal famine of 1943. Well, what can I say. Literally years of work. At least 5,750 edits. Rewritten from top to bottom, from crap to... well, it's a
WP:GA, anyhow. A glowing endorsement by an off-wiki topic domain expert,
Paul R. Greenough. Four attempts at
WP:FA, each of which was... alas... more absurd than its predecessor. On the bright side, special thanks to those who helped in later stages, esp.
Brianboulton and
Fowler&fowler.
