Flag of Switzerland used by Burgundy and Maximilian I. The first flag used as a field sign representing the confederacy rather than the individual cantons may have been used in the Battle of Arbedo in 1422 (notably without the participation of the Canton of Schwyz). This was a triangular red flag with an elongated white cross. The white cross was thus in origin a field mark attached to combatants for identification, and later also to cantonal flags. The Lucerne chronicle of 1513, in battle scenes of the Burgundy wars of the 1470s shows cantonal flags with an added white cross. In this context,
Flag of Sarawak originally made up of a cross, half blue and half red, on yellow, thought to be based on Brooke's coat of arms. There is a controversy on whether the first flag was made up of "purple" and red, or "blue" and red. On 7 May 1870, the colour of the half blue cross was changed to black by the second Rajah, Charles Brooke, and was hoisted on 26 September, the birthday of the then Rajah Muda Charles Vyner Brooke. It was retained as a coat-of-arms on a Blue Ensign when Sarawak was ceded to the British Crown on 1 July
