These warriors for hire have shaped the course of conflicts, driven by gold, glory, and the

From ancient times to modern battlefields, their stories are filled with bravery, treachery,
and incredible feats.
Today we're diving into the fascinating world of mercenaries.
6.
The Ten Thousand
The Ten Thousand were a motley assortment of Greek warriors contracted by Cyrus the
Younger to help oust his brother King Artaxerxes II from the Persian throne.
In 401 BC, the Hellenic soldiers for hire, many of them hardened veterans of the Peloponnesian
War, fought alongside Cyrus and his rebel army in a clash with the king's forces near
Baghdad.
While the Ten Thousand held their own in combat, Cyrus was killed in the battle, and the mercenaries'
generals were double-crossed and murdered while trying to negotiate a retreat.
Under pursuit from Artaxerxes II's troops and hostile natives alike, the surviving Ten
Thousand members were forced to band together and fight their way out of enemy territory.
After electing Xenophon as one of their new leaders, the army embarked on a grueling nine-month
odyssey that took them from the heart of Babylonia to Greece.
Despite facing constant ambushes, punishing weather and famine, they arrived on friendly
soil with nearly three-fourths of their numbers still intact.

The White Company
The White Company was one of the most infamous of the so-called Free Companies, bands of
for-profit soldiers who conducted the lion's share of warfare in 14th century Italy.
The unit first rose to prominence in the 1360s before falling under the command of Sir John
Hawkwood, an Englishman who had been knighted for his service in the Hundred Years' War.
With Hawkwood at the helm, the White Company became known as one of the most elite mercenary
armies in Italy.
Its troops, a cultural hodgepodge of English, German, Breton and Hungarian adventurers,
were renowned for their skill with the long bow and the lance, and they terrified opponents
with their lighting-quick surprise attacks and willingness to do battle during harsh
weather or even at night.
In an era when Italy was splintered between warring city-states and medieval lords, the
men of the White Company made a killing by auctioning their services off to the highest
bidder.

The Swiss Guard
Today, the Swiss Guard is known as striped-uniformed protectors of the Pope in the Vatican, but
their history stretches back to bands of mercenaries that flourished during the Renaissance.
More than one million Swiss adventurers fought in Europe's armies between the 15th and
19th centuries.
These troops were among the first European soldiers to master the use of pikes and halberds
against more heavily armored foes, and by the 1400s, their revolutionary tactics and
sheer ruthlessness had earned them a reputation as the best contract troops money could buy.
A small contingent of 150 Swiss soldiers of fortune began serving as papal bodyguards
in 1506, and the unit endured as the official watchmen of the Vatican even after Switzerland
banned its citizens from working as mercenaries.
Still clad in their brightly colored Renaissance-era uniforms, the Swiss Guards of today must be
Roman Catholics, stand at least 5 foot 6 inches tall, and have a military background.
3.
The Flying Tigers
Officially known as the American Volunteer Group, the famed Flying Tigers were a three-squadron
force of fighter pilots who fought with the Chinese against the Japanese during World
War II.
Eager to impede the Japanese takeover of China while still remaining neutral, President Franklin
D. Roosevelt allowed former U.S. military officer Claire Chennault to quietly recruit
fighter jocks from the ranks of the U.S. Army Air Force.
The risks were high, but so was the pay.
While most Air Force pilots received a salary of around $260 a month, Chennault's mercenaries
earned between $1,600 and $1,750, along with a $1,500 bonus for each Japanese aircraft
they shot down.
Despite flying slower, less maneuverable fighters than the enemy, the Americans downed 296 Japanese
aircraft and destroyed more than 1,300 riverboats, all while only losing 69 planes and some two
dozen men.
2.
The Catalan Grand Company
First organized in 1302 by the adventurer Roger de Flore, the Catalan Grand Company
was primarily composed of rugged Spanish veterans of the War of the Sicilian Vespers in Italy.
Left unemployed at the conflict's end, de Flore and his mercenaries contracted themselves
to the Byzantine Emperor Andronicus II, who brought them to the eastern Mediterranean
to fight off invading Ottoman Turks.
The 6,500 strong Catalans succeeded in sweeping the Turks away from Constantinople, but their
penchant for wanton sacking and looting also drew the ire of the Byzantines.
In 1305, de Flore and some 1,300 of his men were ambushed and killed by another group
of mercenaries in the Emperor's employ.
Rather than disband, the surviving Catalans embarked on one of the bloodiest and most
bewildering adventures in medieval military history.
1.
The Varangian Guard
The descendants of Norsemen who originally ventured south as pirates and traders, the
Varangian Guard were a band of Viking mercenaries paid to serve as the personal bodyguard of
the Byzantine Emperor.
The Guard first took up their post in the late 10th century for Emperor Basil II, who
preferred the axe-wielding barbarians to his more easily corruptible countrymen.
The unit immediately proved useful in putting down a rebellion and they served as Constantinople's
protectors for over 200 years.
At first, the Varangian Guard was almost entirely composed of hard-fighting, hard-drinking Vikings,
but by the late 11th century, their ranks began to be filled out by Englishmen, Normans
and Danes.
Initiates had to demonstrate their prowess in battle and were forced to pay a small fortune
in gold as an entrance fee.
Still, the gifts showered on the Varangians ensured that its members left extremely wealthy
for their loyalty, and some even went on to achieve positions of immense power.
One of the most famous Guardsmen was Harald Hardrada, who later claimed the throne of
Norway.
