Andrew de Chauvigny, cousin to Richard I and overseer of the regulations for the Third Crusade written in Messina in October 1190. He was given the hand of Denise, countess of Devon, daughter and heiress of Ralph VII de Deols by Richard I and married by bishop of Rochester in August 1189.
Andrew wasn’t the luckiest of chaps, he was unhorsed by William Marshall and severely broke his arm when Henry II's rearguard clashed with Count Richard's vanguard outside Le Mans in 1189. Then he broke it again whilst rescuing the earl of Leicester in Palestine in December 1191. However, he was certainly brave. His standard was one of the first raised above the walls of Darum during King Richard I's assault (22 May 1192) and he participated in repulse of Mamluk counter attack at Jaffa - one of only 10 with a horse (August 1192). Finally, in terms of the Third Crusade, he was the commander of first party of pilgrims to Jerusalem.
Rather than replicate the arms of his shield on the caparison, I have chosen to just use the red diamond symbol, which would be easy to distinguish on the battlefield and in line with representations of other caparisons from the period.
