On This Date In History

On July 15, 1965, the unmanned spacecraft Mariner 4 passes over Mars at an altitude of 6,000 feet and sends back to Earth the first close-up images of the red planet.
Launched in November 1964, Mariner 4 carried a television camera and six other science instruments to study Mars and interplanetary space within the solar system. Reaching Mars on July 14, 1965, the spacecraft began sending back television images of the planet just after midnight on July 15. The pictures, nearly 22 in all, revealed a vast, barren wasteland of craters and rust-colored sand, dismissing 19th-century suspicions that an advanced civilization might exist on the planet. The canals that American astronomer Percival Lowell spied with his telescope in 1890 proved to be an optical illusion.
Once past Mars, Mariner 4 journeyed on to the far side of the sun before returning to the vicinity of Earth in 1967. Nearly out of power by then, communication with the spacecraft was terminated in December 1967.

 

 

On July 15, 1918, near the Marne River in the Champagne region of France, the Germans begin what would be their final offensive push of World War I. Dubbed the Second Battle of the Marne, the conflict ended several days later in a major victory for the Allies.
The German general Erich Ludendorff, convinced that an attack in Flanders, the region stretching from northern France into Belgium, was the best route to a German victory in the war, decided to launch a sizable diversionary attack further south in order to lure Allied troops away from the main event. The resulting attack at the Marne, launched on the back of the German capture of the strategically important Chemin des Dames ridge near the Aisne River on May 27, 1918, was the latest stage of a major German offensive, dubbed the Kaiserschlacht, or the “kaiser’s battle”, masterminded by Ludendorff during the spring of 1918.
On the morning of July 15, then, 23 divisions of the German 1st and 3rd Armies attacked the French 4th Army east of Reims, while 17 divisions of the 7th Army, assisted by the 9th Army, attacked the French 6th Army to the west of the city. The dual attack was Ludendorff’s attempt to divide and conquer the French forces, which were joined by 85,000 U.S. troops as well as a portion of the British Expeditionary Force (BEF), most of which were located in Flanders.
When the Germans began their advance after an initial artillery bombardment, however, they found that the French had set up a line of false trenches, manned by only a few defenders. The real front line of trenches lay further on, and had scarcely been touched by the bombardment. This deceptive strategy had been put in place by the French commander-in-chief, Philippe Pétain.
As a German officer, Rudolf Binding, wrote in his diary of the July 15 attack, the French “put up no resistance in front … they had neither infantry nor artillery in this forward battle-zone … our guns bombarded empty trenches; our gas-shells gassed empty artillery positions …. The barrage, which was to have preceded and protected [the attacking German troops] went right on somewhere over the enemy’s rear positions, while in front the first real line of resistance was not yet carried.” As the Germans approached the “real” Allied front lines, they were met with a fierce barrage of French and American fire. Trapped and surrounded, the Germans suffered heavy casualties, setting the Allies up for the major counter-attack they would launch on July 18.

 

On July 15, 1903, the newly formed Ford Motor Company takes its first order from Chicago dentist Ernst Pfenning: an $850 two-cylinder Model A automobile with a tonneau (or backseat). The car, produced at Ford’s plant on Mack Street (now Mack Avenue) in Detroit, was delivered to Dr. Pfenning just over a week later.
Henry Ford had built his first gasoline-powered vehicle, which he called the Quadricycle, in a workshop behind his home in 1896, while working as the chief engineer for the main plant of the Edison Illuminating Company in Detroit. After making two unsuccessful attempts to start a company to manufacture automobiles before 1903, Ford gathered a group of 12 stockholders, including himself, to sign the papers necessary to form the Ford Motor Company in mid-June 1903. As Douglas Brinkley writes in “Wheels for the World,” his history of Ford, one of the new company’s investors, Albert Strelow, owned a wooden factory building on Mack Avenue that he rented to Ford Motor. In an assembly room measuring 250 by 50 feet, the first Ford Model A went into production that summer.
Designed primarily by Ford’s assistant C. Harold Wills, the Model A could accommodate two people side-by-side on a bench; it had no top, and was painted red. The car’s biggest selling point was its engine, which at two cylinders and eight-horsepower was the most powerful to be found in a passenger car. It had relatively simple controls, including two forward gears that the driver operated with a foot pedal, and could reach speeds of up to 30 miles per hour (comparable to the car’s biggest competition at the time, the curved-dash Oldsmobile).
Dr. Pfenning’s order turned out to be the first of many, from around the country, launching Ford on its way to profitability. Within two months, the company had sold 215 Fords, and by the end of its first year the Mack Avenue plant had turned out some 1,000 cars. Though the company grew quickly in the next several years, it was the launch of the Model T in 1908 that catapulted Ford to the top of the automobile industry. The Lizzie’s tremendous popularity kept Ford far ahead of the pack until dwindling sales led to the end of its production in 1927. That same year, Ford released the second Model A amid great fanfare; it enjoyed similar success, though the onset of the Great Depression kept its sales from equaling those of the Model T.

 

 

On July 15, 1806, Zebulon Pike, the U.S. Army officer who in 1805 led an exploring party in search of the source of the Mississippi River, sets off with a new expedition to explore the American Southwest. Pike was instructed to seek out headwaters of the Arkansas and Red rivers and to investigate Spanish settlements in New Mexico.
Pike and his men left Missouri and traveled through the present-day states of Kansas and Nebraska before reaching Colorado, where he spotted the famous mountain later named in his honor. From there, they traveled down to New Mexico, where they were stopped by Spanish officials and charged with illegal entry into Spanish-held territory. His party was escorted to Santa Fe, then down to Chihuahua, back up through Texas, and finally to the border of the Louisiana Territory, where they were released. Soon after returning to the east, Pike was implicated in a plot with former Vice President Aaron Burr to seize territory in the Southwest for mysterious ends. However, after an investigation, Secretary of State James Madison fully exonerated him.
The information he provided about the U.S. territory in Kansas and Colorado was a great impetus for future U.S. settlement, and his reports about the weakness of Spanish authority in the Southwest stirred talk of future U.S. annexation. Pike later served as a brigadier general during the War of 1812, and in April 1813 he was killed by a British gunpowder bomb after leading a successful attack on York, Canada.
