Pre-war deployment........................

On August 21, 1939 the BDU (Dönitz) realized that he could not fulfill all the plans for lack of boats, the Kriegsmarine had very few submarines to sail towards the Atlantic and none of them could be sent to remote areas. So by the evening of this day the situation was as follows:

7 submersibles of the 1st Flotilla assigned to Group West.
4 submersibles of the 2nd Flotilla en route to the Atlantic.
3 submersibles of the 2nd Flotilla en route to the Baltic.
5 Submersibles of the 5th Flotilla en route to the Baltic.
5 Submersibles of the 6th Flotilla en route to the Atlantic.
5 Submersibles of the 7th Flotilla en route to the Atlantic.

On August 22, 1939 at 03:00 hours sailed from Wilhelmshaven the U-30 (Oblt Fritz-Julius Lemp, IWO Oblt Hans-Peter Hinsch, IIWO Lt Friedrich Bothe). This submersible type VIIA and belonging to the 2nd Flotilla was to operate with the U-27 on the northern access of the Irish Sea (Atlantic Operations Order No. 2).

The following submarines sailed en route to the Atlantic:

2nd U-Flotilla: U 28/29/30/33/34
6th U-Flotilla: U 37/38/39/40/41
7th U-Flotilla: U 45/46/47/48/52

On August 23, 1939 at 23:00 hours, and with the storm at the gates, sailed from Wilhelmshaven the U-27 (KpLt Johannes Franz; IWO Oblt Werner Kolb; IIWO Oblt Hermann Beckmann).

Maßnahme Schweden!

Effective since August 24, 1939 came into force the so called Maßnahme Schweden (Measure Sweden), it was intended to prevent Poles ships to escape to the North Sea. Here were engaged the U 31 (Kplt Johannes Habekost, IWO Oblt Heinz-Otto Schulze), U 32 (Kplt Paul Büchel, IWO Oblt Hans Jenisch) and U 35 (Kplt Werner Lott, IWO Oblt Hans-Bernhard Michalowski). These boats sailed towards the port of Memel on August 24, 1939 arriving there on August 26, 1939 and sailed again from the port of Memel on August 27, 1939 with the intention of setting minefields to accomplish the assigned mission.

But the measure was not very effective because the sea mines were not launched and three Polish destroyers (ORP Burza, ORP Gdynia/Grom and ORP Blyskawica) and two Polish submarines reached Great Britain, while other Polish ships arrived in Sweden.

The first round - War with Great Britain and France!

September 3, 1939.

On this day at 19:00 hours the U 30 spotted the British passenger ship Athenia (13,518 ton) sailing in zigzag and dimming. At 19:40 hours the German submersible launched two torpedoes (as per Ubootwaffe KTB), one of which struck the ship and caused it to sink in position 56 ° 44'N - 14 ° 05'W south of Rockall, 112 passengers were killed (many Americans) and 1290 were saved.

Among the important actions on this day, the U 14 probably carried out the first action against an enemy warship, when at 20:22 hours attacked the Polish submarine ORP Sep; considering the traces of wrecks observed in the water, Kplt Wellner radioed the sinking, however the Polish submersible escaped unharmed. Meanwhile the U 18 attacked unsuccessfully the Polish Submersible ORP Zbik, launching a torpedo that just missed the mark.

The sketch below shows the normal routes to Quebec and New York and the spot where the Athenia was torpedoed. What do you think? Anyone have information on why the route that follow the captain.........Was it fear of submarines, following orders?. TIA. Cheers. Raúl M .
