Which Welsh castle surrendered to Yorkist forces on 14 August 1468?

Harlech Castle surrendered to Yorkist forces on 14 August 1468.

Harlech was the last major Lancastrian stronghold in Wales during the Wars of the Roses. After the Yorkist victory at Towton in 1461, the castle remained in Lancastrian hands under its constable, Dafydd ap Ieuan. Its steep rocky position and access to supplies by sea helped the garrison resist for years.

The crisis sharpened in 1468 when Jasper Tudor landed in Wales with French support and used the region as a base for Lancastrian activity. Edward IV responded by ordering William Herbert, Earl of Pembroke, to raise a large army and besiege Harlech. After about a month, the small garrison surrendered on 14 August.

Harlech’s siege is traditionally linked with the Welsh song and march “Men of Harlech,” although the song’s exact historical origins are uncertain. It should not be confused with the castle’s earlier siege during Owain Glyndŵr’s revolt, which ended in 1409.
