Poland’s only seaport captured by Germans
Thursday, September 14, 1939
In Poland... German troops enter Gdynia (the only Polish seaport), west of Danzig. German forces attacking from East Prussia reach open country when they cross the Narew River near Modlin and sweep around Warsaw to begin the encirclement of the Polish capital. Lwow is cut off by German attacks. The German 19th Panzer Corps (Guderian) reaches Brest-Litovsk. Ethnic Ukrainians begin an uprising in Lwow and Stanislawow, attacking small Polish army units in the vicinity.
In Budapest... The Hungarian government refrains from declaring its neutrality on the grounds that it is not threatened by Hitler.
In the North Atlantic... Northwest of Ireland, the carrier, HMS Ark Royal, has a lucky escape from a German submarine, U-39, attack while engaged in an anti-submarine patrol. The U-boat is sunk by 3 British destroyers accompanying the carrier and 43 German crewmen are captured.
In the Soviet Union... The Communist Party official newspaper, Pravda, launches an anti-Polish propaganda campaign with a front-page article deploring the treatment of minorities in Poland.

Dear Franklin:
Replying to your letter of September 12th, am
enclosing herewith a print, which you may retain, of the
map of the land you bought from Fred Wright.
I will try to go over this land tomorrow or Saturday
with William Plog to see if the stakes have been moved or
not, and will let you know what we find.
With kindest regards, I am
Yours very truly,

U-39 or Unterseeboot 39 was a German Type IX submarine of the Kriegsmarine.
Her keel was laid down June 2, 1937, by AG Weser of Bremen. She was commissioned December 10, 1938 with Kapitänleutnant Gerhard Glattes in command.
U-39 conducted one patrol, as part of the 6. Unterseebootsflottille. On September 14, 1939, U-39 was depth charged north-west of Scotland by HMS Faulknor, HMS Firedrake and HMS Foxhound. All 44 crew members survived the sinking, and were taken prisoner by the British.
U-39 was the first of many U-boats to be sunk in World War II, after it unsuccessfully attacked HMS Ark Royal.

U-39
http://en.wikipedia.org/wiki/HMS_Ark_Royal_(91)
On 14 September, Ark Royal received a distress call from SS Fanad Head, which was 200 nautical miles (370 km) away under pursuit from the surfaced U-30.[20] Ark Royal launched aircraft to aid the merchant ship,[20] but was spotted by U-39, which launched two torpedoes.[21] Lookouts spotted the torpedo tracks and Ark Royal turned towards the attack, reducing her cross-section and causing the torpedoes to miss and explode harmlessly astern.[19] Three F class destroyers escorting the carrier began to depth charge U-39, and forced her to the surface.[21] The German crew abandoned ship before U-39 sank—the first U-boat lost in World War II.[21] Ark Royal’s aircraft reached Fanad Head, which was in the hands of a German boarding party.[20] The Skuas unsuccessfully attacked U-30: two crashed when caught by the blast of their own bombs.[20] The U-boat escaped after rescuing the boarding party and the pilots of the downed aircraft (both observers had drowned), and torpedoing the Fanad Head.[20]
Reading the German Communique, now you know why I shed no tears over Dresden.
Guderian-Operations at Brzesc
On 14 September the 10th Panzer Division reported that its forward elements had reached Brzesc. The 3d Panzer Division, which had shifted to the left rear of the 10th Panzer Division, covered the corps’ left flank by pushing reconnaissance elements out in the direction of Kobryn.
The corps commander hurried to join the force that had reached the objective, and the 20th Motorized Infantry Division, its operations against the Polish 18th Infantry Division completed, was shifted eastward to give the Panzer units at Brzesc additional infantry support.
House of Commons debates, 14 September 1939
Mr Campbell Stephen (Glasgow Camlachie)
asked the Minister of Labour whether he is aware that owing to the air-raid signal on 6th September many people were late at their work; and whether he intends to introduce legislation to see that they are not penalized by loss of wages for such periods when their failure to work is due to circumstances outwith their control?
Mr Ernest Brown (Leith)
This question is under discussion in various industries, and I understand that in some cases agreed arrangements have already been made to meet the situation. There is no present intention of introducing special legislation.
Battle of Jaworow-Sadowa begins as encircled Polish troops near Lvov prepare to attempt a breakout.
14 September, 1939-
Japanese troops advance south towards the Chinese port of Changsha. As more Chinese and Japanese troops converge here, 270,000 soldiers will be engaged in fighting in this city over the next few weeks.

Telegram
VERY URGENT
Moscow, September 14, 1939-6 p. m.
SECRET
No. 350 of September 14
Reference your telegram No. 336 of September 13.
Molotov summoned me today at 4 p.m. and stated that the Red Army had reached a state of preparedness sooner than anticipated. Soviet action could therefore take place sooner than he had assumed at our last conversation (see my telegram No. 317 of September 10). For the political motivation of Soviet action (the collapse of Poland and protection of Russian “minorities”) it was of the greatest importance not to take action until the governmental center of Poland, the
Page 93
city of Warsaw, had fallen. Molotov therefore asked that he be informed as nearly as possible as to when the capture of Warsaw could be counted on.
Please send instructions.
I would direct your attention to today’s article in Pravda, carried by DNB, which will be followed by a similar article in Izvestia tomorrow. The articles serve [to prepare] the political motivation mentioned by Molotov for Soviet intervention.

HOLOCAUST NEWS-
September 14, 1939: Jewish New Year.
Przemsysl, Poland- 43 Jews taken, forced to do labor and then shot to death. This is attributed to a Hitler Youth unit attached to 1st Mountain Division.
Einsatzkommando I/1 and I/3 are just 36 hours behind them.
September 14, 1939: Order No.7 of German Civilian Administration transfers all Jewish industrial and commercial enterprises in Poland to “Aryan’ hands.
Thought I’d check in real quick. Been a rough weekend and will likely be a rough week. I’ll try to get caught up tomorrow morning.
I wanted say that I’m sad to report the passing of Brigadier General Kendall Bell, my wife’s uncle. He passed away peacefully Friday evening.
He flew F-105s over Vietnam and also is the author of the book 100 Missions North chronicling his tour of duty (I recommend it for those interested in what pilots when through over Vietnam).
Like I said, I’ll try to get back up to speed tomorrow morning and will get Phase IV of German ops posted too.
