Six American diplomats were in a different building when the Iranian revolutionaries broke into the embassy compound. They managed to evade capture and made it to the Swiss and Canadian embassies which were nearby.
Canadian Ambassador to Iran, Ken Taylor, made arrangements to protect the six diplomats until they could be smuggled out of Iran to freedom.
Canada held its first secret session since World War Two and voted to give the Americans Canadian passports. Using these passports, the six Americans flew to home and safety.
Thanks Canada
