Background: Jan Zizka z Trocnova a Kalicha (Czech pronunciation: ['jan 'ZISka] ( listen); German: Johann Ziska; English: John Zizka of Trocnov and the Chalice) was a Czech general, a contemporary and follower of Jan Hus, Hussite military leader, and later also a Radical Hussite who led the Taborites. Zizka is held to be one of the most renowned military leaders by many historians and today he is widely considered a Czech national hero. He was born in the small village of Trocnov (now part of Borovany) in the Kingdom of Bohemia into an aristocratic family.
Context: Zizka helped develop tactics of using wagon forts, called vozova hradba in Czech or Wagenburg by the Germans, as mobile fortifications. When the Hussite army faced a numerically superior opponent they prepared carts for the battle by forming them into squares or circles. The carts were joined wheel to wheel by chains and positioned aslant, with their corners attached to each other, so that horses could be harnessed to them quickly, if necessary. In front of this wall of carts a ditch was dug by camp followers. The crew of each cart consisted of 16-22 soldiers: 4-8 crossbowmen, 2 handgunners, 6-8 soldiers equipped with pikes or flails (the flail was the Hussite "national weapon"), 2 shield carriers and 2 drivers.  The Hussites' battle consisted of two stages, the first defensive, the second an offensive counterattack. In the first stage the army placed the carts near the enemy army and by means of artillery fire provoked the enemy into battle. The artillery would usually inflict heavy casualties at close range.  In order to avoid more losses, the enemy knights finally attacked. Then the infantry hidden behind the carts used firearms and crossbows to ward off the attack, weakening the enemy. The shooters aimed first at the horses, depriving the cavalry of its main advantage. Many of the knights died as their horses were shot and they fell.  As soon as the enemy's morale was lowered, the second stage, an offensive counterattack, began. The infantry and the cavalry burst out from behind the carts striking violently at the enemy, mostly from the flanks. While fighting on the flanks and being shelled from the carts the enemy was not able to put up much resistance. They were forced to withdraw, leaving behind dismounted knights in heavy armor who were unable to escape the battlefield. The enemy armies suffered heavy losses and the Hussites soon had the reputation of not taking captives.
Question: Were they successful with that method
Answer: The enemy armies suffered heavy losses and the Hussites soon had the reputation of not taking captives.

Problem: Background: Randi was born on August 7, 1928 in Toronto, Ontario, Canada, the son of Marie Alice (nee Paradis) and George Randall Zwinge. He has a younger brother and sister. He took up magic after seeing Harry Blackstone Sr. and reading conjuring books while spending 13 months in a body cast following a bicycle accident. He confounded doctors who expected he would never walk again.
Context: In 1996, Randi established the James Randi Educational Foundation. Randi and his colleagues publish in JREF's blog, Swift. Topics have included the interesting mathematics of the one-seventh area triangle, a classic geometric puzzle. In his weekly commentary, Randi often gives examples of what he considers the nonsense that he deals with every day.  Beginning in 2003, the JREF annually hosted The Amaz!ng Meeting, a gathering of scientists, skeptics, and atheists. The last meeting was in 2015, coinciding with Randi's retirement from the JREF.  James Randi began a series of conferences known as "The Amazing Meeting" - TAM - which quickly became the largest gathering of skeptics in the world, drawing audiences from Asia, Europe, South America, and the UK. It also attracted large percentage of younger folks. Randi has been regularly featured on many podcasts, including The Skeptics Society's official podcast Skepticality and the Center for Inquiry's official podcast Point of Inquiry. From September 2006 onwards, he has occasionally contributed to The Skeptics' Guide to the Universe podcast with a column titled "Randi Speaks." In addition, The Amazing Show is a podcast in which Randi shares various anecdotes in an interview format.  In 2014 Part2Filmworks released An Honest Liar, a feature film documentary, written by Tyler Measom and Greg O'Toole, and directed and produced by Measom and Justin Weinstein. The film, which was funded through Kickstarter, focuses on Randi's life, his investigations, and his relationship with longtime partner Jose Alvarez, a.k.a. Deyvi Pena. The film was screened at the Tribeca Film Festival, at Toronto's Hot Docs film festival, and at the June 2014 AFI Docs Festival in Silver Spring, Maryland and Washington, D.C., where it won the Audience Award for Best Feature. It has since been captioned in ten different languages, shown worldwide, and was also positively received by critics. The film was featured on the PBS Independent Lens series, shown in the U.S. and Canada, on March 28, 2016.  In 2017, he appeared in animated form on Holy Koolaid, in which he discussed the challenge of finding the balance between connecting sincerely with his audience and at the same time tricking/fooling them with an artful ruse and indicated that this is a balance many magicians struggle with.
