Question: The Battle of Nedao involved a group of people who lived when? 

A suicide mission is a task which is so dangerous for the people involved that they are not expected to survive.  The term is sometimes extended to include suicide attacks such as kamikaze and suicide bombings, where the people involved actively commit suicide during execution of the mission.  The risks involved with suicide missions are not always apparent to those participating in them or to those who plan them.  However, for an action to be considered a suicide mission someone involved must be aware of the risks.  A mission that goes horribly wrong is not a suicide mission.  An individual or group taking part in a mission may perceive the risks involved to be far greater than what they believe to be acceptable, while those planning or commanding the mission may think otherwise.  These situations can often lead to refusals to participate in missions on the basis that they are "suicide missions".  Similarly, planners or commanders may be well aware of the risks involved with missions while those participating in them may not. <SEP>  According to European tradition, they were first reported living east of the Volga River, in an area that was part of Scythia at the time; the Huns' arrival is associated with the migration westward of a Scythian people, the Alans. The Huns were a nomadic people who lived in Eastern Europe, the Caucasus, and Central Asia between the 4th century AD and the 6th century AD.  By 370 AD, the Huns had arrived on the Volga, and by 430 the Huns had established a vast, if short-lived, dominion in Europe. <SEP> In Greek mythology, Amycus (Greek: Ἄμυκος ) was a male centaur.  Amycus was the son of Ophion.  There is not much known about Amycus, but he is said to have been involved in the Centauromachy, a battle between the centaurs and the Lapith people; this battle is what the centaurs are best known for.  The battle took place during the wedding of the King of the Lapithae, Pirithous, and his wife Hippodamia.  Amycus' involvement in this battle is recognized in the "Metamorphoses", written by the Roman poet Ovid.  In this work, it is noted that Amycus, along with many other centaurs, was invited to and attended the wedding that turned into a bloody battle.  The centaurs become drunk on wine and attempted to take Hippodamia, along with other Lapith women, as they pleased.  Eurytus, a centaur, could not control himself when the bride, Hippodamia, was presented; he attempted to kidnap and rape her.  He inspired all the drunken centaurs to attack and violate the Lapith women.  Theseus, a friend of Pirithous, stopped the centaur Eurytus, unilimally killing him resulting in the first blood of the battle.  Amycus's role in this battle is of great importance; he was responsible for the first death of one of the Lapith people.  Driven with anger due to the death of the loved centaur Eurytus, Amycus smashed the head of innocent Lapith Celadon with a candlestick.  Pelates from Pella clubbed him to death using a leg from a maple table, sending Amycus down to the underworld Tartarus.  These were the first deaths of the battle between the centaurs and the Lapith people.  The Lapiths ultimately defeated the centaurs and drove them from Thessaly to the northwest. <SEP> The Battle of Nedao, was a battle fought in Pannonia in 454, between Huns and their former vassals.  Nedao is believed to be a tributary of Sava river.
