From Marine 1 website:
"The first report of the GENERAL SLOCUM fire was a telephone message from a citi?zen at 10:11 A.M. This was followed immediately by a message from the Police Department that Officer Cowan, of the 35th Precinct, reported a steam?ship on fire at Hell Gate. The dis?patcher ordered Engine 51 (fireboat) to roll at 10:12. A half minute later Box 2339 was received and transmitted. As phone messages to the Fire Alarm Of?fice in 67th Street brought word of what was happening, Chief Croker ordered the fireboat HEWITT to re?spond from her Brooklyn berth and to stop at the foot of East 67th Street to take him aboard. The SLOCUM fire was fast and furious. When first dis?covered, the steamer was entering Hell Gate opposite Hallets Point. The ves?sel sank near North Brothers Island. Of the more than 1,400 persons aboard, only about 400 were rescued. The death toll reached 1,021. The men of our Department made many rescues but their principal job that day was the recovery of bodies."
