The Union flag was changed in 1801 to include the red saltire of St Patrick, following the Act of Union with Ireland. The Union wreath of roses and thistles was also altered to include shamrocks. By an order of 1844 the King’s Colour was to be the Union flag without any battle honours. The regimental number was to take centre place, in gold, surmounted by Queen Victoria’s Crown.
The Regimental Colour was yellow with the Union flag in the upper canton. The numeral X was within a circle inscribed NORTH LINCOLNSHIRE, surrounded by a Union wreath of roses, thistles and shamrocks. Victoria’s crown was above and the Sphinx and EGYPT beneath, with a spray of laurel leaves. The regiment had been part of the Sutlej Campaign of 1845-46, aka The First Sikh War. They won a battle honour for their part in the battle of Sobraon on 10 February 1846. The honour SOBRAON was granted in June 1847 and placed on the right side of the Colour, with PENINSULA placed on the left.
The size of the Colours had remained unchanged since 1768 (6’6” x 6’2”) and were not reduced until 1855 when the size was 6ft flying by 5’6” on the pike. But three years later the size was again reduced to 4’6” flying by 4’ on the pike. The pike remained almost 10ft tall, with a spearhead on top. This print was reproduced in Cannon’s Historical Record of the 10th, published in 1847.
