1917 – Loretta Walsh becomes first woman Navy petty officer when sworn in as Chief Yeoman.
1918 – General Erich Ludendorff has planned a knock-out blow on the Western Front. He recognizes that, with the imminent arrival of scores of thousands of US troops in France, Germany is likely to lose the war. Ludendorff plans to strike first. He transfers some 70 divisions of troops from the Eastern Front, where the turmoil following the Russian Revolution has effectively ended Russian involvement in the war. In the short term, therefore, Germany has a clear numerical advantage over the British and French. Ludendorff’s plan is to exploit the differences between Britain’s and France’s strategies for facing any major German offensive. He believes the French will give priority to the defense of Paris, while the British are more concerned with defending the ports along the north French coast through which their supplies and troops flow. Ludendorff aims to attack the juncture between the French and British forces in northeast France.
To this end he has three armies, the Seventeenth under General Otto von Below, the Second led by General Georg von der Marwitz, and General Oskar von Huiter’s Eighteenth, prepare for the offensive. These are to advance along a 50-mile front from Arras to St. Quentin and La Fere. This zone is defended byt the British Third Army under General Sir Julian Byng and General Sir Hubert Gough’s Fifth Army. Ludendorff had 63 divisions, many led by elite storm trooper units, earmarked for the attack, while the British can muster just 26. the offensive is code-named Operation Michael but it is also known as the Kaiserschlacht (Kaiser’s Battle).
Operation Michael begins with a sudden five-hour bombardment on the British by 6,000 artillery pieces. They fire both gas and high-explosive shells. Under cover of thick fog the Germans attack, with the specially trained storm trooper units leading the way. The surprise and shock of the onslaught overwhelms the thinly spread British. Gough’s Fifth Army collapses in confusion, exposing the right flank of Byng’s Third Army. However, Bying’s forces, which are holding a narrower front than those of Gough, withdraw across the Somme River in good order. The attackers here, drawn from the German Seventeenth and Second Armies, make significantly fewer gains. Operation Michael will end on April 5th with no decisive victory along these lines on the Somme.
1919 – Navy installs and tests Sperry gyrocompass, in first instance of test of aircraft gyrocompass.
1928 – Coolidge gave the Congressional Medal of Honor to Charles Lindbergh. The Medal of Honor was not always awarded for “courage above and beyond” the call of duty.
1943 –The second military conspiracy plan to assassinate Hitler in a week fails to come off. Maj. Gen. Henning von Tresckow, a member of Gen. Fedor von Bock’s Army Group Center, was the leader of one of many conspiracies against Adolf Hitler. Along with his staff officer, Lt. Fabian von Schlabrendorff, and two other conspirators, both of old German families who also believed Hitler was leading Germany to humiliation, Tresckow had planned to arrest the Fuhrer when he visited the Army Group’s headquarters at Borisov, in the Soviet Union. But their naivete in such matters became evident when Hitler showed up-surrounded by SS bodyguards and driven in one of a fleet of cars. They never got near him. Tresckow would try again on March 13, 1943, in a plot called Operation Flash.
This time, Tresckow, Schlabrendorff, et al., were stationed in Smolensk, still in the USSR. Hitler was planning to fly back to Rastenburg, Germany, from Vinnitsa, in the USSR. A stopover was planned at Smolensk, during which the Fuhrer was to be handed a parcel bomb by an unwitting officer thinking it was a gift of liquor for two senior officers at Rastenburg. All went according to plan and Hitler’s plane took off–the bomb was set to go off somewhere over Minsk. At that point, co-conspirators in Berlin were ready to take control of the central government at the mention of the code word “Flash.” Unfortunately, the bomb never went off at all-the detonator was defective.
A week later on March 21st, on Heroes’ Memorial Day, (a holiday honoring German World War I dead), Tresckow selected Col. Freiherr von Gersdorff to act as a suicide bomber at the Zeughaus Museum in Berlin, where Hitler was to attend the annual memorial dedication. With a bomb planted in each of his two coat pockets, Gersdorff was to sidle up to Hitler as he reviewed the memorials and ignite the bombs, taking the dictator out-along with himself and everyone in the immediate vicinity. Schlabrendorff supplied Gersdorff with bombs-each with a 10-minute fuse. Once at the exhibition hall, Gersdorff was informed that the Fuhrer was to inspect the exhibits for only eight minutes-not enough time for the fuses to melt down.
1944 – US forces moving west from Yalau Plantation link up with Australian forces advancing north, from inland, on the Huon Peninsula.
1945 – The US 8th Air Force targets Me262 fighter bases in western Germany.
1945 – Bureau of Aeronautics initiates rocket-powered surface-to-air guided missile development by awarding contract to Fairchild.
