The simple story that Margaret Thatcher thought HMS Ark Royal remained in service is rejected. The Prime Minister had instead been reassured by the Defence Secretary and Foreign Secretary that there was no serious risk. Britain's ambassador in Argentina was warning that danger did exist, but those warnings were discounted as they moved upward. The episode therefore concerns the filtering of diplomatic intelligence and ministerial advice more than ignorance of the fleet list. The popular anecdote hides the institutional process that shaped prewar assumptions.

The claim that Margaret Thatcher believed Ark Royal was still active obscures a more important failure: senior ministers discounted warnings from Britain's ambassador in Argentina.
