The defenses were organized as follows:
1) Border Post line - The line of defenses built near the border, these were simple blockhouses (some were disguised as houses and barns) designed to give advance warning of an attack.
2) The Support Line - set back 3 km from the border, they would provide the fall back positions for the border defenses. A number of flood zones were in this line of defense.
3) The Main line of resistance. Here were the main fortresses (ouvrages). These were designed to funnel the German offensive and to cause as much damage to the Germans as possible. More had been planned but never built.
The ouvrages were:
Ouvrage Boussois
Ouvrage de la Ferte
Ouvrage Eth
Ouvrage Four a Chaux
Ouvrage Hackenberg
Ouvrage Haut-Poirier
Ouvrage Hobling
Ouvrage Latiremont
Ouvrage Laudrefang
Ouvrage Mauvais Bois
Ouvrage Molvange
Ouvrage Mont des Welches
Ouvrage Rochonvillers
Ouvrage Simserhof
Motorized infantry units monitored the areas in between the ouvrages.
The first part of 1938's Fleet Problem XIX was the Marine landing at Cancun. The landings were divided into two parts. The first landing would be against hastily constructed beach defenses. The defending army troops (actually there were Mexican Military Auxiliary Troops - former Mexican Army soldiers working for the US Military) would have 2 days notice of the landings and would construct beach defenses. The Navy and Marine Air flying off the Ranger would attack those positions for 8 hours before landing.
The umpires considered the first landing a success. This was despite the fact that nearly 1/3 of the Marines were landed on the wrong beach.
The second part of the landings was a different matter. This time the defenders had two weeks to construct beach defenses. Sand, dirt and log blockhouses were built (concrete was not used due to the time constraints) for machine and light to medium artillery. Underwater minefields (unarmed) were laid - the defenders let the umpires know their exact positions. Plenty of barbed wire was laid.
The landings took place at dawn February 17, 1938. The battleship New York and the battle cruiser Puerto Rico, plus several cruisers and destroyers laid down an 18 hour barrage. The umpires were shocked to find 10 Mexican Auxiliaries still inside several of the larger blockhouses. They were deafened from the noise but otherwise unharmed. They had wanted to prove that soldiers could be in those bunkers and still be able to fight. The umpires ruled that the men were unfit for combat.
The umpires ruled that the defending anti-aircraft fire and defending fighters shot down 8 Marine fighters and dive-bombers before they were wiped out. They also ruled that the landings were a success despite protests from the defenders that most of the defenses, including the barbed wire were intact and capable of at least stopping the first wave in their tracks.
The Air Defenses of the Panama Canal
In 1938, there were 8 USAAC Squadrons in the Panama Canal Zone. There were four pursuit squadrons, 2 equipped with Consolidated P-30s and 2 were in the process of switching from the P-26 to the more modern Seversky P-35. The 38th & 54th Pursuit Squadrons (P-30s) were based on the Pacific side of the PCZ based at Balboa Army Air Field.
Task Force 21 was tasked with attacking Forts Amador and Grant and Balboa AAF first and then taking out the locks. TF 21 consisted of the carriers Lexington, Saratoga and United States, with the battle cruisers Alaska, Guam, and Hawaii along with escorting cruisers and destroyers. In all, there were 22 warships approaching Panama.
The 9th Bombardment Squadron also flew out of Balboa flying the B-12. They were tasked with finding TF21. Two of their bombers flew within 10 miles of the TF on the morning of Friday, February 4, 1938 but missed the Task Force. The TF planned a dawn attack for Saturday morning.
At 7:30am, Saturday, February 5, the first wave consisting of 18 Grumman F3F fighters and 24 Great Lakes BG dive bombers crossed the Panamanian coast. The second wave, taking off an hour later, consisted of an additional 20 F3Fs and 18 USMC BG dive bombers. The planes were picked up by an experimental SCR-268 radar being tested in the area. The operators, not knowing of the exercises, merely logged the information and didn't notify their superiors until afterwards.
The umpires ruled the attacks an overwhelming success. The attacking planes, it was determined, had "destroyed or severely damaged" 80% of the defending fighters and bombers on the ground. The umpires also ruled the coastal artillery batteries at Fort Amador were considered badly damaged, Fort Grant's batteries were considered operational with six attacking planes shot down. The nearby locks were ruled moderately damaged.
The umpires also ruled the attack by the 4 "surviving" B-12s was a minor success, ruling 3 hits on the USS Guam., but at the cost of 3 of the bombers being shot down.
The Attack on Pearl Harbor
The Pearl Harbor attack exercise was one of the largest peacetime naval and army exercises ever mounted. More than 300 Army Air Corps, Marine and Naval aircraft and over 100 warships took part. In addition, parts of the Hawaiian Division were used as well.
Shortly after dawn on Sunday, February 28, 1938 several hundred Navy and Marine aircraft flew over Diamond Head and began "attacking" Luke Field on Ford Island, Hickam Field, Schoefield Barrack, and Wheeler Field. Umpires ruled that the attackers had achieved air superiority over the islands. The second wave of attacks, following some 45 minutes after the first wave hit Pearl Harbor.
There were 32 US Navy ships in port at the time, ranging from the battleship USS California down to the submarine USS Argonaut. When the attack began, California was already underway in the harbor, after being attacked numerous times, umpires ruled that she had been sunk in the channel effectively bottling up the harbor.
More senior "battleship" admirals later over ruled the umpires stating that this was supposed to be a realistic test and air power could not inflict that much damage on warships. The Commander-in-Chief, US Fleet canceled the remaining part IV of the Fleet Problem stating that it would be part of the 1939 Fleet Problem.
