My favorite
marine mystery is the
lost Franklin Expedition, although the story is pretty clear that the
men died one by one as they straggled south on the ice after being frozen in at Beechey Island and their ships began to break up. I had the
privilege of visiting Beechey Island on board an ice breaker and saw the graves of a few
men who died early on when their mates still had the wherewithal to dress the bodies, make coffins, dig graves and make grave markers. I believe the Canadian
government exhumed those bodies and found the men had died of lead poisoning from solder in tinned
food. Fascinating story and the beach is still strewn with junk left by
rescue parties dispatched by Lady Franklin for several years before all hope was gone.
