Wednesday 31 July 1940

At around 11:00, Stukas attack the Channel convoys as usual. The attack is near Yarmouth Roads but causes little damage. No dogfights result.
At about 16:00, Luftwaffe planes of JG2 conduct a fighter sweep over Dover soon joined by fighters from JG51. To initiate a response, they attack barrage balloons while they wait for the RAF to come up to meet them. The RAF obliges, and the Germans come off better in the fight, having four planes damaged, while RAF Squadron No. 74 loses three planes and has another badly damaged and likely written off on crash-landing at the base. Such damaged planes remain valuable for spare parts, but they reduce the front-line force. This is one of those cases where some historians will count the RAF losses as three, while others will count them as four.
During the night, there are Luftwaffe raids on Swansea, South Wales, Hornchurch airfield, Shoeburyness, Southend, Brentwood, Ipswich, Wattisham, and Martlesham. Many raids are done by solo raiders.
Total aircraft lost in July 1940 (approximation): Luftwaffe 150 RAF 77. Any figures on losses incorporate various assumptions, such as which damaged aircraft are "lost," and some estimates place Luftwaffe losses much higher. British aircraft production during July is 50% above targets at 496 fighters. The government finds that 1200 planes have been made in the previous quarter, more than in Germany and far outstripping losses. Civilian casualties during the month are 258 killed and 321 wounded.
These kinds of figures are an obvious illustration of why, if the Germans want to invade Great Britain via Operation Sea Lion, sooner is better than later. The Kriegsmarine does not believe it can support an invasion before 15 September, so that is the earliest one can be attempted - but that is highly unlikely as well because none of Hitler's pre-conditions set forth in his 16 July 1940 Fuhrer Directive are being met.
One problem with that reasoning, however, is that German estimates of RAF losses tend to be much higher than the reality - though the reverse often is true as well. This builds a false impression within the Luftwaffe that it is doing better in the battle than it actually is. The Germans, of course, notice the Royal Navy's withdrawal of destroyers from Dover Harbor, and this reinforces their misplaced over-confidence.
I,/JG3 transfers from Grandvilliers to Colembert. The IV (Stuka)/LG 1 gets a new Gruppenkommandeur, Hauptmann Erwin Röde.

U-99 spots another ship, the 6322-ton British freighter Jersey City, in roughly the same area as the Jamaica Progress. This one only takes a single torpedo. There are 43 survivors, two crew perish. This ship is in Convoy OB 191, and the escorts subject U-99 to sustained depth charging that does not damage it. U-99 continues to stalk the convoy.
German raider Pinguin sinks 5358-ton British freighter Domingo de Larringa in the South Atlantic. Thirty crew are taken as prisoners while 8 crew perish.
Norwegian 1298 ton freighter Stalheim hits a mine and sinks in the Bristol Channel.
Royal Navy destroyer HMS Whitshed hits a mine while conducting a sweep in the North Sea. Badly damaged (it lost its bow), the ship is towed back to Harwich.
Convoy OB 192 departs from Liverpool, Convoy HX 62 departs from Halifax.
Canadian armed merchant cruiser HMCS Prince Robert (F 56, Commander Charles T. Beard) is commissioned
Total shipping losses for July 1940:
- 195,825 tons sunk by U-boat
- 70,193 tons sunk by aircraft
- 80,796 tons sunk by surface ships (raiders, etc.)
- 33,598 tons sunk by mines
Operation Hurry, the convoy ferrying Hurricanes to Malta, begins at 08:00. Force H leaves Gibraltar and proceeds from the west during the day, while a separate convoy to the island, BS.2, departs from Suez. HMS Ark Royal carries a dozen Hurricanes for the island. Operation Spark, a diversionary operation off Minorca, is set in motion as well.
The Regia Aeronautica sends a bomber escorted by 7 fighters over the island at 09:43. It is a classic attempt, not to bomb the island, but to bait the defending fighters into combat, and it works beautifully for the Italians. The RAF fighters rise to intervene, and one of the few remaining defending Gloster Gladiators goes down in flames after the forward fuel tank is hit (very scary, flames would be shooting back into the open cockpit). The pilot, Flight Officer Hartley in fighter "Charity," is badly burned after parachuting out and being picked up from the water. The attacking fighters lose a Fiat CR42 fighter, too.
Malta now has just two Gladiators and a Hurricane to defend the island, so Operation Hurry is just in the nick of time.
Anglo/Japanese Relations: The Japanese release four of the 9-12 Britons arrested on espionage charges.
Anglo/US Relations: By telegram sent by US Ambassador Joseph Kennedy to US Secretary of State Cordell Hull, British Prime Minister Winston Churchill urgently requests the "loan" of dozens of destroyers. He notes that the Royal Navy has lost the services of 11 destroyers during the previous 10 days, including four sunk.
US/Latin American Relations: Cruisers USS Wichita (CA 45) and Quincy (CA 39) continue their "Show the flag" mission in Bahia, Brazil.
In an odd act of pettiness, Reichsmarschall Hermann Goering orders that elite fighter unit JG 53 paint over the unit's emblem, the Ace of Spades (German, "Pik As"), on all of its aircraft. The emblem is to be replaced by a red band. Such emblems are marks of pride for the elite formation, and this is an obvious insult. Goering announces that this is to be done to confuse the RAF. However, the real reason (apparently) is that Obstlt Hans-Jürgen von Cramon-Taubadel, the unit's Geschwaderkommodore, has married a woman with Jewish relatives. Some unit members show their displeasure in various ways, such as by painting question marks on their planes. Luftwaffe pilots and ground crew tend to be quite loyal to their commanders. Goering is a well-known dove in terms of prospective military operations - he is very skeptical of plans to invade the Soviet Union - and Goering may do peculiar things like this to show that he is completely "on board" with the Hitler agenda. Goering later lifts the ban.

Vichy France: All French servicemen who join a foreign army - including the British Army - are condemned to death.
|Bloody Wednesday of Olkusz, 31 July 1940.|
British Homefront: A pagan festival of the wheat harvest, Lammas Day, occurs on 1 August, and Lammas Eve is a holiday in and of itself. Magicians and spell-casters from around England direct their vital energies toward the destruction of Hitler. The holiday is full of all sorts of symbolism about reaping what you sow and so forth.
