1780
During the summer of 1780 the regiment was stationed at Shrewsbury, and on the breaking out of the memorable riots in London, it was suddenly called upon to proceed thither. Severe measures being found absolutely necessary to preserve the metropolis from destruction, the suppression of these riots was a painful service to the troops, and the violence of the misguided people was so great, that about 300 rioters fell victims to their own folly, before order was restored.
The Prince of Wales' Dragoon Guards returned to their quarters at Shrewsbury in July, where they continued for some time.
1782
On the 7th of June, 1782, his Majesty conferred the Colonelcy on Lieut.-General Philip Honeywood from the 4th Regiment of Irish Horse (now 7th Dragoon Guards), in the place of Lord Robert Manners, deceased.
1783
After the British Government had recognised the independence of the United States of America, the strength of the army was reduced, and the establishment of the Prince of Wales' Dragoon Guards was decreased 154 men.
1785
The decease of General Honeywood having occurred in January, 1785, his Majesty appointed Major-General Richard Burton Philipson Colonel of the Third Dragoon Guards.
