The action of the novel “The Battle of France” continues the intrigue laid down in the book “The Path to Power”. Queen of England Henrietta Maria of France, after a difficult struggle, achieves the capitulation of all her ill-wishers and finds herself in the cycle of interesting events that swept Europe in 1626-1629. This includes the intense political struggle in England aimed at overthrowing the first minister, the Duke of Buckingham; and the “Chalet Conspiracy” against the French Cardinal Richelieu, in which English and Spanish intelligence played a large role; as well as the intrigues of the Duchess de Chevreuse, the victim of which fell the most famous French duelist, the Comte de Boutville. The political intrigues of the Duke of Buckingham involve the "James Bond of the 17th century" - Walter Montagu, who is opposed by the French "gray eminence" - Joseph du Tremblay. And the conclusion of a political union between England, Spain, the Netherlands, Savoy and Lorraine depends on the diplomatic skill of the brilliant painter Rubens. And finally, the siege of La Rochelle, which shatters the ambitions of the First Minister of England to bring his country to first place in European politics.
