now acknowledged that strategy and tactics were a constant part of medieval warfare.
There are so many factors involved in tactical decisions that one cannot give
comprehensive cover in a brief note but there are countless examples of the use of tactical
positioning—for example on a hill, or with flanking cover, as from marsh or river. The
enefit of surprise was recognised, of using hidden forces and reserves. The past was
studied for information. Geoffrey V of Anjou, while at a siege, studied the
De Re Militari
of Vegetius—a frequently copied work. The bishop of Auxerre expatiated on Vegetius
efore a crowd of knights in c.1200. The nature of weapons and troops available
influenced tactics such as concerted knightly charges, dismounting men-at-arms, use o
missile forces like archers, or defensive pike formations. The importance of training was
understood, as shown in tournaments, or by practice manoeuvres of militias. Armies were
formed from tactical units—major divisions such as battles and lesser groups such as
conrois
or lances, making possible battlefield moves including steady advance, angled
advance, advance in echelon, flanking attack and organised retreat. Mistakes were made
and some commanders lacked tactical ability but medieval warfare usually involved
tactical thinking. The survival of a document on how Agincourt might have been fought
(in the way it never was) shows that tactics were considered before battle as well as
during it. There is evidence for the use of scouts to give advance warning of enemy
movements (as at Brémule), and of messengers to keep the command informed during
attle. Major considerations were how to use available forces, such as mounted knights or
gunpowder weapons, to their best advantage, how best to counter enemy strengths, for
example by taking good positions or presenting obstacles such as
zv280
stakes, trenches or
missile troops, and how best to attack the particular opposition.
UNIFORMS
It is not easy to know when uniform was worn in medieval times though the need to
distinguish two sides was a constant. Ways of doing this, apart from wearing identifiable
clothing, included following a standard, wearing a badge or plume, or using a war cry.
Heraldic arms developed partly to identify an individual or a group during battle. This
partly explains the use of similar arms for a family and its branches—usually fighting on
the same side. The development of groups paid by a single source increased the
likelihood of uniforms, as with mercenary companies. Urban militias were often provided
with uniforms. The men of Tournai in 1340 wore blue jackets and white hats. The
crusader cross was an identifying mark. In the 14th century forces from Wales and
Cheshire wore green and white uniforms. Most medieval uniform was not reserved for
military use but had social significance too. The use of uniforms increased in the final
two medieval centuries. There were some national elements in symbols, like the cross o
St George for English troops, but universal national uniform in the modern sense did not
exist.
VAVASSORS (VAVASSORES)
Lesser vassals, similar in meaning to vassals but generally understood as ‘vassals o
vassals’, called rear-vassals or under-vassals. In the
Bayeux Inquest
of 1133 a
vavassor
was a free tenant with military obligations who performed military service with arms,
armour and a horse.
Vavassors
could hold land, sometimes a fraction of a knight’s fee.
They were found in England, France and Italy. They demonstrate the complexity o
