From the back cover of the Greg Cochkanoff book:
"This was the fate of the S.S. Atlantic, the second ship built by the White Star Line. Constructed forty-two years before the RMS Titanic, the S.S. Atlantic completed eighteen trans-Atlantic crossings before running aground off the coast of Nova Scotia on April 1, 1873. The worst trans-Atlantic marine disaster of the nineteenth century, the sinking of the Atlantic killed over half the nearly 1000 people on board."
From a review of the book:
"Excellent photos, drawings and recovered artifacts from the S.S. ATLANTIC that was wrecked off the shores of Halifax, N.S."
I have a copy of the book on order.
