On Nov. 21, 2013, at 11:27 a.m., a leaky ship arrived in Beirut's port. It never left, and its volatile cargo would lead to tragedy in the city almost seven years later. The Rhosus was loaded with 2,750 tons of ammonium nitrate, which is believed to have blown up most of the port and damaged large parts of the city when it ignited in a warehouse on Aug. 4. The former captain of the ship, Boris Prokoshev, told The New York Times that he heard from other sailors that the Rhosus sank in 2015 or 2016. This time frame turned out to be incorrect.
