Saturday 17 August 1940

A Handley Page Hampden Mark 1 being loaded with 250 lb bombs to which the armorers are fitting fuzes. This particular bomber, No. P1333 "EA-F," is with RAF No. 49 Squadron based at Scampton, Lincolnshire. P1333 participates in the raid on Merseburg/Leuna on 17 August 1940 and is shot down, crash-landing at Breda, Holland.

Battle of Britain: Just like during World War I - a constant reference point for Adolf Hitler - on 17 August 1940 the Wehrmacht imposes an absolute blockade around the British Isles. Any ships whatsoever found within those waters is to be sunk on sight:

Germany, having repeatedly warned these [non-combatant] States not to send their ships into the waters around the British Isles, has now again requested, in a note, these governments to forbid their ships from entering the Anglo-German war zones. It is in the interest of these States themselves to accede to this German request as soon as possible. The Reich Government wishes to emphasize the following fact: The naval war in the waters around the British Isles is in full progress. The whole area had been mined.

This is a highly risky strategy, as President Roosevelt is just waiting for any excuse to enter the war. A few sinkings of US ships would help him to build a case. However, focusing all of the Reich's resources in the air and on the sea in one focused direction makes more sense strategically than a one-armed attack by the Luftwaffe against the RAF that it basically (especially as recent events have shown) cannot win.

Hitler justifies this as retaliating against a "British hunger blockade against German women and children." This has more resonance than it might because of recent comments by US Ambassador to Belgium and Luxembourg (since recalled) on the same theme. One can view this change in strategy as a clear sign that the German high command views the Battle of Britain as going poorly.

In terms of the air campaign, it is a light day despite perfect flying weather. Both sides have taken huge losses and can use the rest. This gives the staff of the numerous RAF airfields devastated in recent days a chance to clean up the debris and level the runways.

There are scattered intrusions by lone Luftwaffe bombers or small groups of bombers. A Junkers Ju 88 from 2./NJG 1 gets lost and is shot down off Spurn Head at 03:00. Another plane is shot down in the Channel. The Luftwaffe drops propaganda leaflets at Welshpool. A few scattered "Freie Jagd" missions by Luftwaffe fighters result in dogfights and victories by JG 51.

The Luftwaffe damages British freighters St. Patrick and Yewkyle in the southern entrance to the Irish Channel (St. George's Channel).

After dark, the Luftwaffe bombs East Suffolk, Warwickshire, Staffordshire, Derbyshire. Liverpool, Coventry, and Birmingham receive attention, with damage to the Liverpool docks. These are a prelude to the "Moonlight Sonata" raids of November. The Bristol Aeroplane Company at Filton and the Avonmouth docks receive their usual bombing raids from over a dozen Heinkel He 111s of II,/KG 27. Overall, bombing accuracy is poor, a problem that afflicts both sides at night, but the Luftwaffe is working on that with new equipment (see below).

While the RAF is holding up magnificently, the strains of the campaign continue to show. There is a growing shortage of experienced pilots, with 68 lost and 70 badly injured in the last five days alone. Air Marshal Dowding requests and receives permission from the Air Ministry to poach pilots from other branches of the RAF for re-training as fighter pilots, and also for further reductions in training time for completely new pilots. Today is a welcome relief, with patrols-flown down substantially.

American Pilot Officer William Fiske perishes of wounds suffered on the 16th. He is the only American fighting in the RAF to perish during the Battle of Britain and is buried in St. Paul's Cathedral.

RAF No. 1 Squadron, staffed by Canadian pilots, becomes operational. RAF No. 310 Squadron becomes operational, staffed by Czechoslovakian pilots, at RAF Duxford. With RAF Tangmere badly damaged in recent days, RAF No. 602 Squadron is moved nearby to Westhampnett.

Wendell Willkie campaigning in his hometown of Elwood, Indiana, on 17 August 1940.

European Air Operations: RAF Bomber Command raids Leuna in eastern Germany (just west of Leipzig), one of its more distant targets, during the night. It is home to the Leunawerke, a huge chemical plant, and is a key oil target due to its refinery. There also are other armaments works there. The Merseburg/Leuna area is amply protected by anti-aircraft guns, and missions there are among the least-favored by Allied bomber crews. The raid, like most early bombing raids, is inaccurate and hits some non-industrial targets.

Another Bomber Command raid, on Boulogne, drops 3 tons of incendiaries and other bombs. There also are the usual raids on individual Luftwaffe airfields throughout northwest Europe.

Battle of the Atlantic: British aircraft carrier HMS Hermes, which was in a collision with armed merchant cruiser HMS Corfu on 10 July, is in Simonstown, South Africa for repairs. The collision has lost the forward 30 feet of its bow. The repairs are scheduled to take months.

Convoy FN 255 departs Southend, Convoy MT 143 departs Methil, Convoy FS 255 departs from the Tyne.

British submarine HMS Utmost (N 19, Lt. John H. Eaden) and corvette HMS Coreopsis (K 32, Lt. Commander Alan H. Davies) are commissioned.

Battle of the Mediterranean: The British Admiral Cunningham sends a large task force, codename MB 2, centered around battleships HMS Malaya, Ramillies and Warspite and cruiser HMS Kent to bombard the Italian at Bardia, Libya (including nearby Fort Capuzzo). The bombardment commences at 06:58 and lasts for 22 minutes. Force A has the Warspite and Kent, and Force B has the Malaya and Ramillies.

The Italian artillery cannot reach the British battleships, which can stand far offshore and fire with impunity. The Italians under Marshal Graziani essentially abandon the fort after the attack. The Regia Aeronautica attacks the British flotilla without success and loses several planes.

British submarine HMS Rorqual lays mines off Cyrenaica.

It is a quiet day in Malta. The local government via the War Office authorizes increased local ground forces composed of volunteers, with tighter supervision. They also are unpaid but full members of His Majesty's Armed Forces (else they could be shot as spies or partisans after an invasion). Governor-General Dobbie also urgently requests supplies.

The 18 August 1940 papers are full of news of Wendell Willkie's acceptance speech, Hitler's blockade of England, and a "Gay Pageant" in Chicago.

British Somaliland: The Italian forces under Lieutenant-General Carlo De Simone close up on the British blocking forces and begin attacks late in the morning. The Black Watch launches a successful bayonet charge to hold the position. Another Italian force at Bulhar, 40 miles west of Berbera, is approaching as well, but light cruiser HMS Ceres bombs the road and temporarily stops the advance. After dark, the Black Watch at Barkasan gives up its positions and marches to the transports at Berbera, where the evacuation is in its final stages.

Winston Churchill has a somewhat unrealistic view of what could have been accomplished in British Somaliland. The Italian forces outnumber the colonial British forces, buttressed by a few elite formations such as the Black Watch, by a huge amount, and they also are better equipped with tanks, artillery, and aircraft. Churchill wants a victory or at least a successful defense under impossible circumstances that, of course, are part of his own creation.

After hearing of Churchill's attitude, Middle East Commander General Wavell responds:

A bloody butcher’s bill is not the sign of a good tactician.

This is not a very political statement, and Wavell must understand this when he makes it.

Wavell, though, is absolutely correct and has handled the campaign with extreme competence (British casualties are minimal), but this incident starts turning the tactically challenged (but undeniably inspirational) Churchill against the extremely competent (but strategically overwhelmed) General Wavell. There are many in the British government, including Sir Alan Brooke, who view Churchill as a loose cannon when it comes to military strategy, and this is an example. To his credit, Churchill retains General Wavell in command despite the strategic setback, showing a high degree of maturity and even wisdom.

What is ironic given Churchill's petulance is that the British defeat in British Somaliland could have been far, far worse. There are strong indications that the Italian aggressors have held back there (and perhaps at Malta) in hopes that a peace deal under discussion quietly at the Vatican might bear fruit.

President Roosevelt and Mackenzie King of Canada on 17 August 1940.

Applied Science: The Luftwaffe is using radio signals to try to guide their night bombers - called X-Gerät, a successor to Knickebein - with little success. This involves three separate radio beams called "Rhine," "Oder," and "Elbe" which the navigators would hear at different points of the mission and use as course corrections. Results are good for the time being, but the British immediately deploy countermeasures (the Germans unwisely use 45 MHz, a BBC frequency, tipping the British off) of varying effect.

US/Canadian Relations: President Roosevelt and Prime Minister William Mackenzie King meet at Ogdensburg, New York. They sign an agreement - the Ogdensburg Agreement - for a Permanent Joint Board on Defense.

British Government: The Duke of Windsor, safely out of Europe, is sworn in as Governor-General of the Bahamas. He remains under deep suspicion by other elements of the British government for alleged pro-German leanings.

US Military: Destroyers USS Wake and Wainwright continue their "Show the flag" mission in South America, departing Bahia, Brazil for Pará, Brazil.

Greece: The country partially mobilizes its armed forces in response to recent Italian provocations such as the sinking of the light cruiser Helle (Elli). A Greek investigation reveals fragments of an Italian torpedo in the wreckage of the Helle.

Afghanistan: The Afghanistan Parliament begins.

The "War of the Lapel Badges" breaks out in Luxembourg (Federal Archive, Christian Minzlaff, August 1940).

Luxembourg: Around this date, the Spéngelskrich ("War of the Pin-badges") begins in occupied Luxembourg. Citizens wear patriotic lapel pins (think American flags) as an expression of defiance at the German authorities who are trying to eliminate any vestiges of Luxembourg as an independent state.

France: The occupation authorities requisition ("donate") all private watercraft.

American Homefront: Wendell Willkie formally accepts the Republican nomination for President in his hometown of Elwood, Indiana. He decries the "unfruitful political adventures" that led to France's downfall.
