1778 – The Battle of Crooked Billet begins in Hatboro, Pennsylvania. The Battle of Crooked Billet was a battle in the Philadelphia campaign of the American Revolutionary War fought near the Crooked Billet Tavern (present-day Hatboro, Pennsylvania). In the skirmish action, British forces under the command of Major John Graves Simcoe launched a surprise attack against Brigadier General John Lacey and three regiments of Pennsylvania militia, who were literally caught sleeping. The British inflicted significant damage, and Lacey and his forces were forced to retreat into neighboring Bucks County. The British troops arrived at Crooked Billet at daybreak. Simcoe had planned a “pincer”-type attack, with his troops attacking from the north and east, and Abercromby’s troops from the south and west. Lacey’s pickets, in place to warn against any type of threat, noticed the British troops, but failed to fire off a warning shot for fear of being killed or captured. Neilsen sent a runner back to the camp to raise the alarm, but he never arrived. Surprised and outnumbered, the militia were soon routed and forced to retreat into Warminster. As a result of this engagement, the American forces lost ten wagons full of much-needed supplies, and Lacey had almost 20% of his force killed, wounded or taken prisoner. Lieutenant Nielson, the officer in charge of the pickets, was court-martialed and cashiered from the militia for disobeying orders.
1785 – Kamehameha I, the king of Hawaiʻi, defeats Kalanikūpule and establishes the Kingdom of Hawaiʻi. The Battle of Nuʻuanu, fought on the southern part of the island of Oʻahu, was a key battle in the final days of King Kamehameha I’s wars to unify the Hawaiian Islands. It is known in the Hawaiian language as Kalelekaʻanae, which means “the leaping mullet”, and refers to a number of Oahu warriors driven off the cliff in the final phase of the battle. The Battle of Nuʻuanu began when Kamehameha’s forces landed on the southeastern portion of Oʻahu near Waiʻalae and Waikiki. After spending several days gathering supplies and scouting Kalanikupule’s positions, Kamehameha’s army advanced westward, encountering Kalanikupule’s first line of defense near the Punchbowl Crater. Splitting his army into two, Kamehameha sent one half in a flanking maneuver around the crater and the other straight at Kalanikupule. Pressed from both sides, the Oʻahu forces retreated to Kalanikupule’s next line of defense near Laʻimi. While Kamehameha pursued, he secretly detached a portion of his army to clear the surrounding heights of the Nuʻuanu Valley of Kalanikupule’s cannons. Kamehameha also brought up his own cannons to shell Laʻimi. During this part of the battle, both Kalanikupule and Kaiana were wounded, Kaiana fatally. With its leadership in chaos, the Oʻahu army slowly fell back north through the Nuʻuanu Valley to the cliffs at Nuʻuanu Pali. Caught between the Hawaiian Army and a 1000-foot drop, over 400 Oʻahu warriors either jumped or were pushed over the edge of the Pali (cliff). In 1898 construction workers working on the Pali road discovered 800 skulls which were believed to be the remains of the warriors that fell to their deaths from the cliff above.
