The English Royal Navy's relationship with Scotland during the years preceding the Union of 1707 is usually cast as problematic in scholarly discussion, with the navy viewed as the enforcer of an embargo on Scottish trade with France. This study examines the Scottish use of Royal Naval convoy in the first years of the War of Spanish Succession through to 1707, focusing on the North Sea region. It adds nuance to security issues surrounding the parliamentary union by arguing that convoys to Scotland were more frequent than generally acknowledged, an improvement on the situation in the 1690s, and that when combined with the small Scottish navy, provided coverage that largely met Scottish needs. As a result, in a period of otherwise fierce debate, naval protection for Scotland was relatively uncontroversial. Convoy was therefore an unusual, if belated, success for regal union, and that success meant that Scots were more deeply enmeshed in the English system of maritime security than has been often been credited.
