Battle of Yanling: The Battle of Yanling () was fought in 575 BC between the states of Chu and Jin at Yanling during the Spring and Autumn period of ancient China.  On the Jin side, Xi Qi (郤錡) commanded the right wing whilst Luan Shu (欒書) commanded the center with Han Jue (韓厥) on the left .  Prior to the battle, Shi Xie wanted to avoid battle on the basis that external enemies are necessary for internal peace.  The Chu army had the numerical advantage but with the exception of the King's personal guard, it was in poor condition.  The Chu army was also commanded by Zifan (子反) and Zichong (子重), who hated each other.  Following Luan Shu's advice, the Jin army took a defensive posture instead of going on the offensive.  By dawn the Jin armies were deployed behind a marsh and ditch, which impeded Chu troops.  Fen Huang, a Jin officer, pointed out that the best Chu troops in the center was bogged down by the marsh, leaving the flanks to be held only by badly disciplined 'wild tribes of the south'.  Jin chariots then charged both Chu flanks, scattering the enemy.  They then proceeded to attack the center, which contained the Chu King commanding his troops.  Although the Chu King's life was endangered a couple of times, Jin officers let him escape as a sign of respect.  However, he was wounded by an arrow and his army was driven back.

Battle of Walk: The Battle of Walk on July 8, 1657 between forces of Sweden commanded by Friedrich von Löwen on one side, and Russian forces led by stolnik Matvey Sheremetyev, who for the first time in his career commanded an army by himself, on the other side.  The largest part of the Russian army disobeyed Sheremetyev and left the battle at the beginning, forcing him to rely on the 250 reiters of Colonel Denis Fonvizin, who played the key role in the breakthrough and allowed the rest of the army to escape.  The Swedish forces won the battle, and according to their sources they defeated an army of 8,000 men, 32 standards, banners and other field declarations had been captured in the battle and 1,500 Russians were dead or wounded along with their commander Matvey Sheremetyev, who later died in captivity.  However, a recent analysis of Russian 17th-century archive documents related to the battle demonstrates that the entire Russian force, most of which escaped, consisted of only 2,193 men, 353 additional troops failed to arrive in time, and even Tsar Alexis I in his correspondence expected his army to be no larger than 3,000, while the casualties included 108 killed, 28 wounded, 5 captured.  The Swedish declaration has been criticized by Oleg Kurbatov, an expert in the Russian military history of the 17th century, as often tendentious and inaccurate in its description of the Russian army and having inflated numbers.
