Agincourt
The English king waited some time for an answer to a challenge he had sent to the Duke of Aquitaine to decide their quarrel by single combat; but Aquitaine cared more for pleasure than for fighting, and sent no answer to the cartel. It was open to Henry to have proceeded by sea to Calais, and it was the advice of his counsellors that he should do so; but the king declared that the French should never say that he was afraid to meet them, and that as the country was his by right he would march wherever he pleased across it; and so, after leaving a thousand archers and five hundred men-at-arms under the command of the Duke of Exeter, he set out on the 6th of October on his adventurous journey.

Accounts differ as to the number that started with him, some French historians put it as high as 17,000, but it is certain that it could not have exceeded nine thousand men, of whom two thousand were men-at-arms and the rest archers. Now, while the siege of Harfleur had been going on, the arrangements for the embarkation of the troops and stores carried out, and the town put in a state of defence, troops had been marching from all points of France at the command of the French king to join him at Rouen, so that here and in Picardy two great armies were already assembled, the latter under the command of the constable.
