The relative quiet of the Tatar attacks on Russia in the late 30s and early 40s of the 17th century is undoubtedly due to the occupation of Azov by the Don Cossacks.

Input: Consider Input: Passage: Henry V returned to France and went to Paris, then visiting Chartres and Gatinais before returning to Paris. From there, he decided to attack the Dauphin-held town of Meaux. It turned out to be more difficult to overcome than first thought. The siege began about 6 October 1421, and the town held for seven months before finally falling on 11 May 1422. At the end of May, Henry was joined by his queen and together with the French court, they went to rest at Senlis. While there, it became apparent that he was ill , and when he set out to the Upper Loire, he diverted to the royal castle at Vincennes, near Paris, where he died on 31 August 1422. The elderly and insane Charles VI of France died two months later on 21 October 1422. Henry left an only child, his nine-month-old son, Henry, later to become Henry VI. On his deathbed, Henry V had given the Duke of Bedford responsibility for English France . The war in France continued under Bedford's generalship and several battles were won. The English won an emphatic victory at the Battle of Verneuil . At the Battle of Bauge, Clarence had rushed into battle without the support of his archers. At Verneuil, the archers fought to devastating effect against the Franco-Scottish army. The effect of the battle was to virtually destroy the Dauphin's field army and to eliminate the Scots as a significant military force for the rest of the war.
