As soon as Holder arrived back in England, he was ready to turn around and go back to New England to fulfill his mission. He was of sufficient means to finance an expedition, but a ship was needed. Holder asked the master of the "Speedwell" to return his group to Boston, but Locke would not do it in the face of a 100-pound fine. However, Holder found a Quaker ship builder named Robert Fowler who had just finished a small barque and given it the name "Woodhouse". Fowler was willing to offer the small craft for the trans-Atlantic trip, feeling he had been "divinely commissioned". Without any knowledge of navigation, he offered to captain the vessel to America "on the Lord's service". When the ship sailed, Fowler was one of 17 people aboard, of whom he and five others were crew members, consisting of three men and three boys. Among the eleven passengers were several who had been on the earlier "Speedwell" mission, including Holder and Copeland, but also including William Robinson, who would later be hanged as the first of the four Boston martyrs.
