Armies (1388) in a miniature from
Jean Froissart,
Chroniques Scottish victories in the late thirteenth and early fourteenth centuries have been seen as part of a wider "
infantry revolution", that saw a decline in the primacy of the mounted knight on the battlefield. However, it has been pointed out that Scottish medieval armies had probably always been dependent on infantry forces. In the late medieval period Scottish men-at-arms often dismounted to fight beside the infantry, with perhaps a small mounted reserve, and it has been suggested that these tactics were copied and refined by the English, leading to their successes in the Hundred Years' War. Like the English, the Scots deployed mounted archers, and even spearmen, who were particularly useful in the mobile raids that characterised border warfare, but like the English they fought on foot. By the second half of the fourteenth century, in addition to forces raised on the basis of common service and feudal obligations, money contracts of
bonds or
bands of manrent, similar to English
indentures of the same period, were being used to retain more professional troops, particular
men-at-arms and
archers. There were attempts to replace spears with longer pikes of to in the later fifteenth century, in emulation of successes over mounted troops in the Netherlands and Switzerland, but this does not appear to have been successful until the eve of the Flodden campaign in early sixteenth century. There were smaller numbers of archers and men-at-arms, which were often outnumbered when facing the English on the battlefield.
Fortification , perhaps the first fortification in the British Isles to take account of gunpowder artillery: the large D-plan bastion towers can be seen on either wing After the Wars of Independence, new castles began to be built, often on a grander scale as "
livery and maintenance" castles, to house retained troops, like
Tantallon, Lothian and
Doune near Stirling, rebuilt for
Robert Stewart, Duke of Albany in the fourteenth century. were of the
tower house design. Smaller versions of tower houses in southern Scotland were known as
peel towers, or pele houses. The defences of tower houses were primarily aimed to provide protection against smaller raiding parties and were not intended to put up significant opposition to an organised military assault, leading historian Stuart Reid to characterise them as "defensible rather than defensive". They were typically a tall, square, stone-built, crenelated building; often also surrounded by a
barmkyn or
bawn, a walled courtyard designed to hold valuable animals securely, but not necessarily intended for serious defence. They were built extensively on both sides of the border with England, and James IV's forfeiture of the
Lordship of the Isles in 1494 led to an immediate burst of castle building across the region. Gunpowder weaponry fundamentally altered the nature of castle architecture, with existing castles being adapted to allow the use of gunpowder weapons by the incorporation of "keyhole" gun ports, platforms to mount guns and walls being adapted to resist bombardment.
Ravenscraig, Kirkcaldy, begun about 1460, is probably the first castle in the British Isles to be built as an artillery fort, incorporating "D-shape" bastions that would better resist cannon fire and on which artillery could be mounted. Towards the end of the period royal builders in Scotland adopted European Renaissance styles in castle design. The grandest buildings of this type were the royal palaces in this style at
Linlithgow,
Holyrood,
Falkland and the remodelled
Stirling Castle, begun by James IV. A strong influence from France and the Low Countries can be seen in the fashionable design of a quadrangular court with stair-turrets on each corner. However, these were adapted to Scottish idioms and materials (particularly stone and
harl).
Siege engines and artillery The Wars of Independence brought the first recorded instances of major mechanical artillery in Scotland. Edward I used a range of
siege engines, which were carefully constructed, transported, deployed, dismantled and stored for reuse. This began with the siege of
Caerlaverock Castle in 1300. Here, after the failure of an initial assault, a small rock-throwing engine was employed, while three large engines (probably
trebuchet, using a counter-weight mechanism), were constructed. Their destruction of walls demoralised the garrison and forced a surrender. Edward's armies deployed several such engines, often named, with "
Warwolf", one of 17 used in the capture of
Stirling Castle in 1304, being the best known (currently considered the largest trebuchet ever built). They also deployed lighter bolt-shooting
balistas, belfry
siege towers and on one occasion a covered sow. Some of these were supplied by Robert Earl of Carrick, the future Robert I, who was present on the English side. Scottish armies, with more limited resources and expertise tended to rely on assault, blockade and subterfuge as siege tactics. Robert I is known to have employed siege engines against the English, but often with little success, as at
Carlisle in 1315 where his siege tower floundered in mud. The disparity in siege technology has been seen as resulting in a policy of castle destruction by Robert I. The English probably had projectile gunpowder artillery in the 1320s and the Scots by the next decade. The first use by the Scots was probably against Stirling Castle in 1341. The Stewarts attempted to follow the French and English crowns in building up an artillery train. The abortive siege of Roxburgh in 1436 under James I was probably the first conflict in which the Scots made serious use of artillery. James II had a royal gunner and received gifts of artillery from the continent, including two giant bombards made for
Philip the Good, Duke of Burgundy, one of which,
Mons Meg, still survives. Although these were probably already outdated on the continent, they represented impressive military technology when they reached Scotland. James II enthusiasm for artillery cost him his life and demonstrated some of the dangers of early artillery, when a gun exploded at the siege of Roxburgh in 1460. James III also experienced ill-fortune, when artillery sent from
Sigismund, Archduke of Austria sank in a storm en route to Scotland in 1481. James IV brought in experts from France, Germany and the Netherlands and established a foundry in 1511. Edinburgh Castle had a house of artillery where visitors could see cannon cast for what became a formidable train, allowing him to send cannon to France and Ireland and to quickly subdue
Norham Castle in the Flodden campaign. However, his 18 heavy artillery pieces had to be drawn by 400 oxen and slowed the advancing Scots army, proving ineffective against the longer range and smaller calibre English guns at the
Battle of Flodden.
Navy '', the largest ship in the world when launched in 1511 English naval power was vital to
Edward I's successful campaigns in Scotland from 1296, using largely merchant ships from England, Ireland and his allies in the Islands to transport and supply his armies. Part of the reason for Robert I's success was his ability to call on naval forces from the Islands. As a result of the expulsion of the Flemings from England in 1303, he gained the support of a major naval power in the North Sea. James I took a greater interest in naval power. After his return to Scotland in 1424, he established a shipbuilding yard at
Leith, a house for marine stores, and a workshop. King's ships were built and equipped there to be used for trade as well as war, one of which accompanied him on his expedition to the Islands in 1429. The office of
Lord High Admiral was probably founded in this period. In his struggles with his nobles in 1488 James III received assistance from his two warships the
Flower and the ''King's Carvel
also known as the Yellow Carvel
. The king acquired a total of 38 ships for the Royal Scottish Navy, including the Margaret, and the carrack Michael
or Great Michael''. The latter, built at great expense at Newhaven and launched in 1511, was in length, weighed 1,000 tons, had 24 cannon, and was, at that time, the largest ship in Europe. Scottish ships had some success against privateers, accompanied the king in his expeditions in the islands and intervened in conflicts Scandinavia and the Baltic. In the Flodden campaign the fleet consisted of 16 large and 10 smaller craft. After a raid on Carrickfergus in Ireland, it joined up with the French and had little impact on the war. After the disaster at Flodden the Great Michael, and perhaps other ships, were sold to the French and the king's ships disappeared from royal records after 1516. ==See also==
