England might have put roughly 30,000 effective troops into the field after one or two weeks, although it may have been short of field artillery compared with the Spanish force. Spain would also need time to disembark, organize, and concentrate its invasion army. The Tilbury force and trained bands assembling from London could obstruct a rapid advance during that vulnerable interval. The argument does not assume that every militiaman immediately equalled Parma's veterans. It compares the defender's local mobilization timetable with the practical tempo of a large amphibious landing.
