Answer based on context:

The appearance of Joan of Arc at the siege of Orléans sparked a revival of French spirit, and the tide began to turn against the English. The English laid siege to Orléans in 1428, but their force was insufficient to fully invest the city. In 1429 Joan convinced the Dauphin to send her to the siege, saying she had received visions from God telling her to drive out the English. She raised the morale of the troops, and they attacked the English redoubts, forcing the English to lift the siege. Inspired by Joan, the French took several English strongholds on the Loire. The English retreated from the Loire Valley, pursued by a French army. Near the village of Patay, French cavalry broke through a unit of English longbowmen that had been sent to block the road, then swept through the retreating English army. The English lost 2,200 men, and the commander, John Talbot, 1st Earl of Shrewsbury, was taken prisoner. This victory opened the way for the Dauphin to march to Reims for his coronation as Charles VII, on 16 July 1429. After the coronation, Charles VII's army fared less well. An attempted French siege of Paris was defeated on 8 September 1429, and Charles VII withdrew to the Loire Valley.

How many years after the English laid siege to Orleans did they attempt to lay siege to Paris?
