Thanks again, Jeff, Maj.Heyward, Mike, Konrad, Mark and Al.
I really enjoy studying 18th & 19th century uniforms. Generally speaking, the British Army in the mid 18th century wore dark gaiters on campaign and white ones for more formal occasions such as parade, review etc.
Much of the uniform info. for the atire at Culloden comes form the famous battle painting by Morier, which shows Barrell's 4th in white gaiters. - Stuart Reid, in his great book ''Like Hungry Wolves'' states that this painting, commissioned by Cumberland, was most likey done about 1753 - about 7 years after the battle -and is portraying uniform details of that date, and not the those of 1746. ( Keep in mind that this painting, commissioned by Cumberland well after the battle itself, is a kind of propaganda piece, aggrandizing his victory - and portraying his troops in Dress uniform with white gaiters. A common practice by artists of that era.)
Now, there is another painting by Morier of Cumberland himself on horseback. This portait was believed to be painted shortly after the battle in 1746. In the background of this painting is a line of his troops in black gaiters, firing at oncoming Highlanders. ( So here we have a painting being done in the same year of the battle and showing King George's troops in the standard campaign atire of black gaiters. )
I'm surmising black gaiters were worn at Culloden as was the standard practice for troops on campaign- but the big Morior battle painting ''An Incident in the Rebellion of 1745'' showing the King's troops in white gaiters is a popular but possibly less than accurate image of the battle. - Ken
