Raleigh Croshaw accompanied Claiborne on his explorations and, with just a few men, successfully defended a remote trading outpost up on the Potomac River in the 1622 attack. Captain Raleigh Croshaw was in the Potomac River trading in a small bark, commanded by Captain Spilman. There an Indian stole aboard and told them of the massacre, (1622) and that Opchanacanough had been practicing with his King and Country to betray them, which they refused to do, but that the Indians of Werowocomoco had undertaken it. Captain Spilman went there, but the Indians after seeing that his men were so vigilant and well armed, suspected that they had been discovered, therefore, to delude him, they gave him such good deals in trade, that his vessel was soon nearly overloaded".
