for their long spears, including the Scots and the Flemish. Spears usually were used in tightly ordered formations, such as the shield wall or the schiltron. To resist cavalry, spear shafts could be planted against the ground. William Wallace drew up his schiltrons in a circle at the Battle of Falkirk in 1298 to deter charging cavalry; this was a widespread tactic sometimes known as the "crown" formation. Thomas Randolph, 1st Earl of Moray used a circular schiltron on the first day of the Battle of Bannockburn. However, the rectangular schiltron was much more common and was used by King Robert the Bruce on the second day of the Battle of Bannockburn and in the Battle of Old Byland when he defeated English armies. Throwing spears became rarer as the Middle Ages drew on, but survived in the hands of specialists such as the Catalan Almogavars. They were commonly used in Ireland until the end of the 16th century. Spears began to lose fashion among the infantry during the 14th century, being replaced by pole weapons that combined the thrusting properties of the spear with the cutting properties of the axe, such as the halberd. Where spears were retained they grew in length, eventually evolving into pikes, which would be a dominant infantry weapon in the 16th and 17th centuries. Cavalry Cavalry spears were originally the same as infantry spears and were often used with two hands or held with one hand overhead. In the 12th century, after the adoption of stirrups and a high-cantled saddle, the spear became a decidedly more powerful weapon. A mounted knight would secure the lance by holding it with one hand and tucking it under the armpit (the couched lance technique) In combination with a lance rest, this allowed all the momentum of the horse and knight to be focused on the weapon's tip, whilst still retaining accuracy and control. This use of the spear spurred the development of the lance as a distinct weapon that was perfected in the medieval sport of jousting. In the 14th century, tactical developments meant that knights and men-at-arms often fought on foot. This led to the practice of shortening the lance to about .) to make it more manageable. As dismounting became commonplace, specialist pole weapons such as the pollaxe were adopted by knights and this practice ceased. Introduction of gunpowder The development of both the long,
