The failure no doubt gave fresh strength to Prince Henry.

In the opening of 1412 he had been discharged from the Council and Clarence set in his place at its head; he had been defeated in his attempts to renew the Burgundian alliance, and had striven in vain to hinder Clarence from sailing.

The break grew into an open quarrel.

Letters were sent into various counties refuting the charges of the Prince's detractors, and in September Henry himself appeared before his father with a crowd of his friends and supporters demanding the punishment of those who accused him.
The charges made against him were that he sought to bring about the king's removal from the throne; and "the great recourse of people unto him, of which his court was at all times more abundant than his father's," gave colour to the accusation.

Henry the Fourth owned his belief in these charges, but promised to call a Parliament for his son's vindication; and the Parliament met in the February of 1413.
