Carthaginian army They are first mentioned in the mid-4th century BCE in
Sardinia and during the conquest of
Selinunte (409 BCE) in the context of the
Second Sicilian War.
Diodorus Siculus places them among Carthaginian fighters during the capture of
Agrigento and, already in the
Third Sicilian War, in the Battle of Ecnomus (310 BCE), under the command of
Hamilcar, son of
Gisco. According to chroniclers,
Hannibal had approximately 2000 Balearic slingers, positioned at the forefront of his army during the early stages of the
Italian campaign, responsible for initiating the fight to harass the Romans. It is noteworthy that the Balearic slinger contingents were explicitly mentioned in Hannibal's troop distribution before leaving command of the Carthaginian territory in the
Iberian Peninsula to his brother
Hasdrubal, to whom he entrusted 500 Balearic slingers. Hannibal attached great importance to these troops and protected them throughout the campaign as irreplaceable soldiers. The reason for their military effectiveness lay in the greater range and precision of the sling compared to the
bow.
Roman army After the Roman conquest of the Balearic Islands, historical sources again mention the slingers, now integrated into the Roman army.
Gaius Sallustius informs us of Balearic slingers among Roman troops fighting in
Numidia against
King Jugurtha (111–105 BCE). Caesar mentions Balearic slingers as fighters in the
Gallic Wars around 56 BCE, fighting alongside other elite troops such as
Numidian
cavalry and
Cretan archers. == Military function ==
