Historically, no single shot can be cited as the first shot of the battle or the war. Shots were fired earlier at Lexington, Massachusetts where eight Americans were killed and a British soldier was slightly wounded, but accounts of that event are confused and contradictory. The North Bridge skirmish did see the first shots by Americans acting under orders, the first organized volley by Americans, the first British fatalities, and the first British retreat.

On March 25, 1866, a battle ensued in the Plaza de Armas in the center of Chihuahua City between the French imperial forces that were guarding the plaza and the Republican forces led by General Terrazas.

After their loss at the Battle of Sacramento, the remaining Mexican soldiers retreated south, leaving the city to American occupation. Almost 300 Mexicans were killed in the battle, as well as almost 300 wounded. The Americans also confiscated large amounts of Mexican supplies and took 400 Mexican soldiers prisoners of war.

paragraph_text: On 30 November the Russian squadron entered the harbor from the northwest in a triangular formation.

The shells fired by Russian guns immediately set Ottoman ships on fire. Panic-stricken sailors found firefighting efforts difficult amidst continued fire and almost constant shrapnel. After about 30 minutes of  combat the Ottoman frigate was shot full of holes and ran aground when her cable was cut. Imperatritsa Maria then attacked the 44-gun frigate Fazli Allah, which caught fire and grounded. Meanwhile, the other Russian ships engaged the Nizamie and Damiad, which were grounded. The Ottoman frigate Navek Bakhri exploded and sank along with the corvette Guli Sephid.Only one Ottoman vessel, the 12-gun paddle frigate Taif, managed to escape the battle while all the others were either sunk or purposely run ashore to prevent sinking.

paragraph_text: The first non-stop transatlantic crossing was made by the British airship R34 in 1919. Regular passenger service resumed in the 1920s and the discovery of helium reserves in the United States promised increased safety, but the U.S. government refused to sell the gas for this purpose. Therefore, H2 was used in the Hindenburg airship, which was destroyed in a midair fire over New Jersey on 6 May 1937. The incident was broadcast live on radio and filmed. Ignition of leaking hydrogen is widely assumed to be the cause, but later investigations pointed to the ignition of the aluminized fabric coating by static electricity.
