He alone was free from the slightest suspicion of corruption and venality, and he speedily made enemies among his colleagues by the open contempt which he manifested for their gross corruption.
Although he had taken so prominent a part in bringing King William to England, Monmouth soon became mixed up in all sorts of intrigues and plots.

He was already tired of the reign of the Dutch king, and longed for a commonwealth.

He was constantly quarreling with his colleagues, and whenever there was a debate in the House of Lords Monmouth took a prominent part on the side of the minority.

In 1692 he went out with his regiment of horse guards to Holland, and fought bravely at the battle of Steenkirk.

The campaign was a failure, and in October he returned to England with the king.
For two years after this he lived quietly, devoting his principal attention to his garden and the society of wits and men of letters.
