Harlech Castle, built in the 13th century by King Edward I of England to help control the rebellious Welsh, is located in the town of Gwynedd in the north of Wales. The song “March of the Men of Harlech” (Rhyfelgyrch Gwyr Harlech) was composed to commemorate the seige of the castle in 1486 by the forces of Edward IV. That traditional march has been arranged into a fanfare and march for brass quartet by Gene Milford. An optional horn part has been included to substitute for trombone I, and trombone II may also be played on euphonium.
