Needless to say the First Afghan War was between Imperial India and Afghanistan, wayback in 1842 and with a disasterous retreat from Kabul. Taken from: http://www.britishbattles.com/first-...l-gandamak.htm

The First Afghan War provided the clear lesson to the British authorities that while it may be relatively straightforward to invade Afghanistan it is wholly impracticable to occupy the country or attempt to impose a government not welcomed by the inhabitants. The only result will be
failure and great expense in treasure and lives.

The British Army learnt a number of lessons from this sorry episode. One was that the political officers must not be permitted to predominate over military judgments.
