At 1:45 a.m. EST on July 7, 1924, while the leaders of the White House were still hotly discussing the form in which the German Navy would attack the East Coast of the United States, the officers and men of the U.S. Army on the U.S. side of the U.S.-Mexico border had begun to taste the bitter fruits of war.

McCammy is a tiny town in the southern U.S. state of Texas, about 2,000 kilometers from the U.S.-Mexico border. Since the end of the Mexican War, the only thing of interest here has been the U.S. Army barracks near the town. It's called McCamie Barracks, and the locals know it as a military airfield, because the people in the town have several planes taking off and landing there almost every day, sometimes twenty or thirty, and the humming sound is a little irritating, but what worries the residents of the southern United States is the gangs on the other side of the border. Although the former Villa bandits did not cross the border to kill people and set fires after the end of the Mexican Civil War, they became more and more dangerous with the strong support of the Germans.

At this moment, most of the townspeople had heard the news of Germany's declaration of war on the United States from the radio, but many had never imagined that a large number of German warplanes had already crossed the border and were coming towards them.

The first to spot the incoming group was a squadron of American fighter jets that had been ordered to take off from McCammy for a border guard patrol after news of the German declaration of war. Before the four P-9A fighters had even reached the border, they found a large flock of black "crows" flying on the opposite side, and regardless of the huge gap in the performance of the fighters of the two sides, just seeing that the other side was far more numerous than their own, the American pilots hurriedly turned around and slipped away. At this time, except for a few reconnaissance planes, the vast majority of American fighters did not have any radio equipment installed on them, and it was not until these four planes hurriedly landed at the McCammy base that the commander of the air force at the base learned the news of the invasion of the enemy aircraft group -- although the border post had discovered the German aircraft group earlier, they did not directly report the information to the air force base, and when the alarm was reported from the post and finally arrived at McCammi, the attack of the German aircraft group was probably already started.

"Sound the alarm!"

It was the only order given by Colonel Sorensen, the commander of the McCammy base, before the German fleet attacked, less than five minutes after the fighter squad returned to base. More than forty German fighters lowered their altitude and approached McCamie. At this time, four fighter planes and 16 other military planes that had just landed were parked on both sides of the runway of this aviation base, and there were also five reconnaissance planes, eight fighters, and four biplane and twin-engine transport planes parked in the shed hangar. Just to protect the native aircraft industry. The U.S. Army and Navy continue to send orders to several local aircraft companies such as Boeing and Kodis, and if you consider it from the perspective of the technical department alone, it is very uneconomical to do so, so even after the end of the South American War, the United States still imports a considerable part of its military aircraft from Germany every year, and the German government does not refuse to allow the export of local aircraft.

No sooner had the terrible sirens sounded than the air raids of German fighters and attack aircraft began. Twenty-five Junkers-Heinkel D fighters of the 4th Squadron of the 7th Fighter Wing of the Luftwaffe and the 2nd Fighter Wing of the Overseas Dispatch Army launched air strikes against McCammy, and 6 Vulture D attack planes and 14 Vulture DD attack planes of the 1st Squadron of the 7th Attack Aircraft Wing of the Luftwaffe Overseas Dispatch Army. Considering that the first wave of attack planes was likely to be intercepted by American fighters, Colonel Hugosperer, commander-in-chief of the German aviation forces in Mexico, incorporated 200 fighters and 100 attack planes into the first wave of fighters to quickly break the US air resistance and attack the opponent's airfield. The task of destroying targets at the airfield was mainly entrusted to a second wave attack group consisting of three fighter squadrons, two attack aircraft squadrons and four bomber squadrons.

But as the battle progressed. The Germans were surprised to find that there were less than 30 US warplanes on patrol duty in the long US-Mexico border area, and even after the discovery of the German aircraft group intruding, less than two squadrons of US planes were taken off from various airfields to intercept. The two sides engaged in only brief air battles in southeast Texas and southern Arizona, and the quality and courage of the American pilots at the beginning of the war were not complimentary, and the first wave of German planes flew to the American airfield in little time.

Since the Americans did not desperately resist, the task of the German pilots became simpler. At McCammi, vultures scrambled to drop their bombs on the U.S. planes parked on both sides of the runway, defenseless. As the Luftwaffe's tallest all-metal aircraft and the first attack aircraft, the Vulture D has been in test flight for 8 years now, and with the emergence of alternative aircraft, this biplane attack aircraft is gradually withdrawing from the Luftwaffe's ground combat sequence, but it is still one of the weapons that Germany is strictly prohibited from exporting, and all retired aircraft are either converted into trainer aircraft or mothballed as reserve aircraft. Although the action is somewhat clumsy. However, the four 7.92 mm machine guns carried by the Vulture D and the three 50-kilogram aerial bombs under the belly of the vulture were very powerful, and after replacing the high-horsepower engines, the speed of these attack planes was increased to 250 kilometers per hour.

McCamie, after all, is an air base close to the border, and in addition to two squadrons of fighters, there are six air defense positions around the airfield. The fighters that did not take off could only stop on the ground and be beaten, but the soldiers in charge of the air defense had not yet conceded defeat, and soon after the German air raids began. Anti-aircraft fire from the ground finally began to threaten the low-flying German fighters. In fact, as early as when the air raid sirens sounded, the American soldiers in all positions had already begun to prepare, but like Washington, the people here were also unprepared for war, and the soldiers had to hurriedly lift the canvas covering the anti-aircraft guns and anti-aircraft machine guns, and then move the whole box of ammunition from the ammunition depot. In the air defense positions a little north of the base, three 7.62-mm machine guns and two 12.7-mm heavy machine guns were fighting happily, and the bullets hit one of the German fighters as a ringing, and just when the US soldiers thought they were about to shoot down the first German plane, a single-wing attack plane swooped down from the other direction, and it was not until a distance of more than 20 meters that the three bombs in the abdomen were dropped at once. After the violent explosion, the American soldiers covered in blood fell to their positions one by one, and the machine guns that were still firing hard just now looked up helplessly at the sky.

After that, the monoplane quickly pulled up the nose of the plane, and a string of bullets rising from the ground staggered across its wing.

This aircraft is the successor to the Vulture D, the Vulture DD attack aircraft with an inverted gull lower wing design, which is also the army version of the German Navy's Junkers Ju-DD dive bomber, with a single engine and two seats, and a maximum speed of 330 kilometers per hour. The attack radius is 700 km, two 50 kg and one 100 kg high-explosive bombs can be mounted under the belly and wings, and two 7.92 mm machine guns are equipped in the wing position, and there is also a 7.92 mm machine gun firing in the passenger seat, which can be used for dive bombing with a depression angle of 70 degrees.

After the attack planes had finished dropping their bombs, the fighters that had been hovering over the airfield also joined in destroying the US military bases, using their machine guns and machine guns to strafe the unexploded fighters on both sides of the runway.

About 20 minutes later, a second wave of air raiders appeared in the southern sky, and the German fighters and attack planes that had finished their torture reluctantly flew south. By this time, there was smoke rising from Mercam. More than half of the warplanes parked on both sides of the runway became burning fires. Most of the rest were paralyzed by bullets, three of the six anti-aircraft positions were leveled, and the remaining anti-aircraft machine guns groaned weakly like sick people. Several 127-mm anti-aircraft guns were still firing tirelessly at German aircraft, but unfortunately their rate of fire was too slow, and the shells were powerful enough, but they could do nothing against fighters and attack aircraft flying at low altitudes.

In this way, with only 3 fighters and attack aircraft on the ground, the first wave of German air attack aircraft successfully completed the scheduled task, and the air attack effect was better than expected. Immediately afterward, a second wave of 225 warhawks began to carry out air strikes on the remaining targets, the most important of which was the airship anchorage in the northern suburbs of San Antonio, which is nearly 200 kilometers from the border. Located 450 kilometers from Paredon, the largest air base in northeastern Mexico, the Americans considered it relatively safe, so when the war broke out, they moored 52 military airships of various types from the Navy's 4th Airship Group at the San Antonio airship base.

At 2:30 p.m. on 7 July, Washington reacted after learning that the southern states had been subjected to a large-scale air attack by the German and Mexican air forces: the warplanes stationed at the airfields of the southern front line were immediately transferred to the second-tier airfields, and the 2nd and 4th airship clusters of the Navy stationed in the south immediately moved to the border to deal a head-on blow to the invading enemy.

When the order reached the San Antonio airship base, the base fighters and airship crews sprang into action, as it was Monday. Most of the officers and men who had gone on vacation on weekends had returned to their bases, so the commanders at least did not have to worry about their lack of strength. In addition, the airship unit and the airship base have always received the attention of Washington and the Admiralty, and their personnel quality and equipment allocation are outstanding in the army and navy, so in just half an hour, more than a dozen airships have completed their combat preparations and taken into the air, and a squadron of fighters taking off from Austin has also rushed to escort them. It was also at this time that the airship base suddenly sounded an alarm.

It turned out that the airship carrying out the alert mission in the air had spotted a group of planes flying from the southwest, and although it was possible that it was an American fighter plane that had been transferred from the front-line airfield to the hinterland, the commander of the airship base, Brigadier General Jonaden, still decisively ordered the air raid alarm to be issued. This time, the only squadron of 18 P-5 fighters and 15 airships that have been lifted into the air can be put into operation in the vicinity of the entire San Antonio airship base, and only one of these 15 airships is a two-hull Beechcraft type "air carrier", and it is the one responsible for patrolling and guarding, and there are 6 such airships in the base, but they also need more preparation time to upgrade and enter the battle with their huge hulls and 8 carrier-based aircraft.

The group of planes coming from the southwest approached quickly, judging from the direction of their flight, they should have come towards this airship base, and Brigadier General Jonaden, who was standing in the command tower of the base, anxiously watched the situation of the entire base - the crew was basically on the edge of the airship, and with the assistance of the service personnel, the airship pod was loaded with ammunition and fuel, and the huge ammunition depot with reinforced concrete structure was crowded with soldiers and trucks waiting to receive ammunition, and the same situation was also on the gun depot. When the German offensive was imminent, the combat readiness of the entire base was less than halfway through.

Brigadier General Jonaden had only one thought in his mind at this time: I hope that the airship that had already entered the combat position could temporarily block the German attack!

As the German aircraft fleet approached, light fighters took off one after another from the only "Beechcraft" in the sky, this scene somewhat relieved the Americans below - although these P-4 fighters carried by airships can only stay in the air for an hour, but their speed, maneuverability and agility are even better than the German Hummingbird fighters, and the firepower of the two 7.92 mm machine guns is also comparable to that of the Hummingbird. A lot of confidence comes from this kind of aircraft - one-on-one or many-to-many air combat with Germany's main fighters, the P-4 with a speed of up to 350 kilometers per hour can have the upper hand, plus they only need to return to the nearest airship carrier to replenish fuel and ammunition, and the frequency of sorties in the battle is much higher than that of those land-based fighters who must return to the airport to replenish, so the generals of the US side have always claimed that 10 "Beechcraft" full of fighters can seize air supremacy on the battlefield from the German Hummingbird fighters of two groups.

If the main fighter of the Luftwaffe is the Hummingbird, the Americans may really be able to realize this "prophecy", and the Luftwaffe is indeed equipped with more than 900 Hummingbird fighters as the outside world knows, but in fact this kind of fighter has long become a training aircraft for fighter pilots, although the current Luftwaffe only has more than 500 Junkers-Heinkel D, Messerschmidt IV and Black Hawk IV fighters, but it has more than 4,000 skilled fighter pilots. With the domestic aircraft factories operating at full capacity for these three new fighters, within three months the Luftwaffe will have more than 4,000 Junkers-Heinker, Messerschmitt and Black Hawks!

Eight P-4s bravely rushed towards a huge German fleet of 30 fighters, 15 attack planes and 40 bombers, like newborn calves fearlessly and ignorantly rushing towards a tiger with sharp claws and teeth.
