A Sailor's War
In the Second World War, my grandfather was in the Royal Navy. He wrote the names of the places he visited on the spreader bar of his hammock. This page presents a series of interactive maps showing those places along with commentary generated using Google Gemini. The maps were created in Python using Plotly Graph_Objects and Scattergeo.

A Sailor's War: Tracing the Royal Navy's Footsteps Across Theatres
The list of locations visited by a member of the British Royal Navy during World War II paints a vivid picture of the global reach and diverse responsibilities of the service during the conflict. From the vital supply lines of the Atlantic to the fiercely contested shores of the Mediterranean and the support bases back home, these places represent key nodes in the Allied war effort.
The Atlantic Lifeline
The presence of multiple ports along the US East Coast – New York, Jersey City, Baltimore, Norfolk, and nearby Asbury Park and White Stone, VA – underscores the critical importance of the transatlantic supply route. New York and Norfolk served as massive hubs for the organization and departure of convoys carrying essential Lend-Lease materials, troops, and supplies to Britain and other fronts. The Royal Navy, alongside the Royal Canadian Navy and later the US Navy, bore the primary responsibility for escorting these convoys through the perilous, U-boat infested waters of the North Atlantic. The Battle of the Atlantic was the dominating factor all through the war, and victory was the prerequisite for all Allied military action in Europe. Ports like Norfolk, a major US Navy fleet base, and the industrial centres of Baltimore and Chicago (supplying components via inland waterways) provided the logistical backbone and repair facilities crucial for sustaining this effort. Mid-ocean, Bermuda, with its Royal Naval Dockyard, acted as a strategic linchpin for refuelling, repairs, and coordinating the anti-submarine patrols that hunted the U-boat wolfpacks.
Turning the Tide in the Mediterranean
The cluster of locations in North Africa – Oran, Arzew, Mostaganem, and Algiers in Algeria; Sousse, Bizerte, Sfax, Menzel Bourguiba in Tunisia; and Tripoli in Libya – highlights the RN's central role in Operation Torch (November 1942) and the subsequent Tunisian Campaign. Operation Torch, the Anglo-American invasion of French North Africa, relied heavily on the Royal Navy for transporting troops, providing covering fire, and overcoming initial resistance, particularly the naval engagements at Oran. A sailor involved might have witnessed the landings or participated in the subsequent build-up. Securing North Africa was vital for opening the Mediterranean to Allied shipping and providing a springboard for invading Southern Europe. Algiers became the Allied Force Headquarters, while captured ports like Bizerte (a major naval base) and Tripoli (requiring extensive harbour clearance by RN teams) became crucial forward bases. The clearance of Tripoli harbour was described as a monumental task: "The harbour was a shambles... blocked by sunken ships and shattered docks. Royal Navy salvage teams worked tirelessly... essential for the Eighth Army's advance." (Paraphrased from accounts of port clearance operations).
The Italian Campaign: Amphibious Warfare
From North Africa, the focus shifted to Sicily and Italy. The visits to Syracuse, Augusta Bay, Palermo, Catania, and Messina reflect participation in Operation Husky (July-August 1943), the invasion of Sicily. Augusta Bay, in particular, became a huge Royal Navy anchorage. Following Sicily's fall, the campaign moved to mainland Italy. Reggio Calabria marks Operation Baytown, the British Eighth Army's crossing. Salerno (Operation Avalanche) saw one of the most critical and hard-fought Allied landings, where RN warships provided indispensable gunfire support to troops pinned down on the beaches. Naples and Taranto, major Italian naval bases, were secured and transformed into primary Allied logistical hubs for the grinding campaign up the Italian peninsula. The landings at Anzio and Nettuno (Operation Shingle, January 1944) represented another major amphibious effort, heavily supported by the RN, attempting to break the stalemate further north. Maintaining the Anzio beachhead under constant enemy fire was a testament to the tenacity of the naval forces supplying it.
Supporting Liberation and Home Base
The inclusion of Cherbourg points to the post D-Day operations in Normandy (June 1944 onwards). Though captured by US forces, Cherbourg was a vital deep-water port needed to supply the massive Allied armies in France. The Royal Navy played a significant role in clearing mines and obstructions from its harbour, enabling the logistical floodgates to open. Finally, Belfast represents the home front contribution. As a major shipbuilding centre (Harland and Wolff) and an essential base for Atlantic escort groups operating out of the Western Approaches, Belfast was critical throughout the war for building, repairing, and sustaining the fleet.
Conclusion
This geographical footprint traces a path through some of the most pivotal campaigns of World War II. The sailor who visited these places would have experienced the breadth of the Royal Navy's wartime duties: the monotonous vigilance of Atlantic convoy escort, the high-stakes drama of amphibious landings under fire in the Mediterranean, the logistical challenges of operating captured ports, and the industrial might supporting the war effort from both sides of the Atlantic. Each location represents a piece of the complex mosaic of naval warfare that was essential to the eventual Allied victory.
