The English were becalmed in port and unable to manoeuvre. On 1545, the French galleys advanced on the immobilised English fleet, and initially threatened to destroy a force of 13 small galleys, or "rowbarges", the only ships that were able to move against them without a wind. The wind picked up and the sailing ships were able to go on the offensive before the oared vessels were overwhelmed. Two of the largest ships, the "Henry Grace à Dieu" and the "Mary Rose", led the attack on the French galleys in the Solent.
