The Departure

USS Flasher (SS-249), Dorado's sister boat, on sea trials in 1943. Dorado would have been configured very close to this when she left for war. NARA photo #80-G-450241 via Navsource.net.
On the morning of October 6, 1943, Dorado backed smartly out of her slip at Submarine Base New London, Groton, CT., put on some left rudder, and swung her stern to the north and up river. Expertly timing the swing, LCDR Schneider, present on the bridge with several other crewmen, ordered zero rudder and all stop. He then ordered "all ahead two thirds" and Dorado began her trip down the Thames River, headed to Long Island Sound and eventually the Atlantic Ocean.

She passed under the U.S. Route 1 bridge, with the venerable structure lifted open to allow the boat to pass underneath. She passed the main Electric Boat facility on her port beam, and a little further downstream she passed the Victory Yard where she was built. Men and women toiling in the cool October air on Dorado's sister subs paused for a moment, proudly acknowledging their handiwork as the submarine passed. They wished her luck as she headed off to war.

Fishing vessels hailed her as she passed the mouth of the Thames and Schneider rang up an ahead standard bell with turns for 14 knots. The bridge watch team kept a wary eye on the Fisher's Island and Montauk ferries as they passed, with a little maneuvering left and right intended to keep the ferries at a safe distance. Clearing Fisher's Island she made a slight turn to the southeast, putting her on course to pass down the middle between Montauk Point on her starboard side and Block Island on her port. Down below in the control room the Quartermasters and the Navigator were busy piloting the submarine, shooting bearings with the periscope to land-based navigation aids, using those bearings to triangulate their position on the chart. With Montauk Point on their starboard quarter, they took their "point of departure", i.e. the last confirmed land-based navigational fix, and headed out into the blue Atlantic.

Dorado's orders for the first leg of her voyage is called a Movement Order, or MOVORD. Dorado's MOVORD contained seven waypoints, Able to George. They would route her out into the Atlantic and south towards the Caribbean. Her destination was Submarine Base Coco Solo, on the Atlantic side of the Panama Canal near the city of Colon.
