Problem: In 1426 the Hussites were again attacked by foreign enemies. In June 1426 Hussite forces, led by Prokop and Sigismund Korybut, significantly defeated the invaders in the Battle of Aussig. Despite this result, the death of Jan Žižka caused many, including Pope Martin V, to believe that the Hussites were much weakened. Martin proclaimed yet another crusade in 1427. He appointed Cardinal Henry Beaufort of England as Papal Legate of Germany, Hungary, and Bohemia, to lead the crusader forces. The crusaders were defeated at the Battle of Tachov. The Hussites subsequently invaded parts of Germany several times, though they made no attempt to occupy permanently any part of the country. Korybut was imprisoned in 1427 for allegedly conspiring to surrender the Hussite forces to Sigismund of Hungary. He was released in 1428, and participated in the Hussite invasion of Silesia. But after a few years, Korybut returned to Poland with his men. Korybut and his Poles, however, did not really want to leave; but the Pope threatened to call a crusade against Poland if they did not.

Problem: Thomas Wentworth, now the Earl of Strafford, became a leading adviser to the King. He threw himself into Charles's plans with great energy and left no stone unturned to furnish the new military expedition with supplies and money. The Scots under Leslie and Montrose crossed the River Tweed, and Charles' army retreated before them. In a short time, the invaders overran the whole of Northumberland and County Durham . Charles had to leave the two counties in Scots hands as a pledge for the payment of Scots expenses when he agreed to peace and signed the Treaty of Ripon in October 1640. The impoverished King had to summon another parliament to grant him the supplies which he needed to make that payment; this Long Parliament attacked his Government, impeaching  his chief supporters, Strafford and Laud. It sat until purged in 1648. In the hopes of winning Scottish support, Charles went to Scotland in the autumn of 1641 where he gave titles to Leslie and Argyll, and accepted all the decisions of the General Assembly of 1638 and of the Scottish Parliament of 1641, including confirming the right of the Parliament to challenge the actions of his ministers. He had now withdrawn all the causes of the original dispute, but within a year his disputes with the English Parliament would lead to civil war.
Answer this question based on the article: How did Charles make the payment of Scots expenses that he had pledged to with the Treaty of Ripon, by capturing counties in Scotland or by summoning another parliament to grant supplies?
A: summoning another parliament to grant supplies
