The Battle of Tunga, Leyte, the Philippines - October 1944

The map for the Battle of Tunga, Leyte, the Philippines. The village of Tunga is at dead centre. Each 1 x 1 cm square on the map represents 100 metres. The map was contructed in layers using Photoshop, with a modern-day satellite photo of the area as the bottom layer to serve as a guide. I cut out small squares and rectangles to represent the footprint of each maneuver element (usually a company). US units are outlined in blue; Japanese in red. This shows the initial deployment as told to me by the commanding players.

This wargame was not based on a specific historical action, but was simply a convenient way to get elements of my 15mm Japanese collection on the table. I chose this setting because the US Army did the fighting (and I don't have Marines in my collection yet), and they were able to call on armoured support, making for a more interesting game.

We used my home-brew rule set, Hail of Lead (HOL) to play this out. HOL uses 30-minute game turns, and the smallest element (team, or stand) represents a platoon of infantry or approximately five vehicles or towed weapons.

On the above map, elements of American 24th Infantry Division are preparing to attack up the main road from the south as part of operations to clear the Leyte Valley of the Japanese 16th Infantry Division. At the start of the battle the players were in the grip of fog of war: neither side knew the specific location or strength of the other.

The default terrain on the table is "clear cover" terrain, meaning that teams use clear movement rates, get the benefit of soft cover, and line-of-sight is limited to only 25cm (one fourth normal LOS). I'm no expert on the Leyte Valley, but if you look at the satellite maps you see gently undulating ground dotted with palms, clusters of foliage, and all manner of light cover. A video-conference game demands simplicity, so I went for this broad-brush approach. Clusters of light jungle are considered difficult ground for movement purposes, they block LOS, and LOS within them is limited to 3cm. River is passable to all teams, but vehicles may only cross it A) via a stable bridge, or B) cross-country with an engineer team present.

The game table measures five by six feet, or 150 x 180 cm. This view is roughly from the south.

This game was played via Zoom video conferencing during the self-isolation period of the Covid-19 pandemic. My lounge (living room) was set up as a command centre, the game table being watched by a cell phone serving as a webcam on a stationary tripod. I used a second cell phone as a roving webcam. This setup worked well for the players, who remarked that they hardly needed to consult their own maps.

During the course of the game, players relayed their deployment, orders and movement in secret to me, and I plotted all the action on the paper map. When a unit was spotted by the enemy, it was placed on the game table.

Speaking of players, we had two Japanese (based in California) and three Americans (based in Texas and California). Also there were three or four observers, who provided peanut-gallery entertainment for the group (banter being an important part of wargaming).

US forces laid out on a cutting board. The 1st Battalion, 19th Infantry Regiment is to the left; 2nd Battalion is to the right. Note M4 Sherman tanks and combat engineers attached to the companies of the 1/19th. Not pictured are six off-table artillery batteries; three 105mm, three 155mm.

Japanese forces in neat rows. 1st Battalion, 9th Infantry Regiment to the left. 2nd Battalion on right. The infantry are bolstered by light tanks and a couple of batteries of 47mm anti-tank guns. Not pictured are two off-table 105mm artillery batteries in support. On-table support includes various infantry guns and a couple of 81mm mortar teams.

US Victory Conditions:

·      Clearing the four villages along the main (paved) road is a minor victory. A village is cleared when no enemy teams occupy any of its footprint.

·      Clearing the four villages and repairing both bridges is a clear victory.

·      Clearing the four villages, repairing both bridges, and clearing the main road is a major victory. The road is considered cleared so long as there are no Japanese teams within 25cm of it (within LOS or otherwise).

Any other result is a temporary Japanese victory.


Turn one saw a general advance of three US reinforced infantry companies. The American CinC opted to attach tanks, engineers and machine-gun teams to the infantry. The combat engineers served two important functions: first, flamethrower support; and second, the tanks required engineers to cross the river.


B Company crossed the river to the east under fire from a 75mm infantry gun battery stashed in light jungle to the north. US artillery thoughtfully provided a smoke screen.

Japanese 75mm infantry gun falls back into the jungle after taking brisk fire from the Sherman and infantry.

B Company rushes the enemy gun...and you can guess the result.


C Company and A Company move up toward the river and uncover two reinforced Japanese infantry companies dug in on the opposite river bank! 

C Company falls back to their starting point with heavy losses. Note burning Sherman (no American Civil War reference intended). The black "krump" markers indicate that the Americans did not take this lying down, and called four artillery batteries on the entrenched enemy. However, Japanese saving rolls were right on point. The defenders weren't budging...yet.


 Both US companies fell back with some losses, but Japanese 2nd Company was well-nigh destroyed.

One surviving platoon of 2nd Company hides in the jungle.


Japanese 1st Company drops back into the jungle and disappears. The Americans send up two reconnaissance elements to screen the front of their village while combat engineers move up to the first river bridge. The two bridges on the main paved road must be repaired to get vehicles across them. And it would be a good thing for victory conditions.


The US engineers come under fire from concealed 3rd Company (also entrenched). The engineers are wiped out before repairs are completed. The recon retires to the safety of the village in case of a hasty Japanese counter-attack.



B company continues their grand tour of the Japanese east flank. Enemy fire whips them from the village just across the river, but their superior firepower dominates this particular contest. (Not shown: a Japanese 47mm anti-tank battery pops out of cover to try for the Sherman, but instantly regrets it. The same thing happens to a Type 89 I-Go "medium" tank with ambush ambitions.)

The situation advancing into turn seven. I incorrectly marked the companys of US 2nd Battalion as A, B and C. They ought to be E, F and G. Mea culpa!

A second Type 89 I-Go tank is discovered on the road by a reconnaissance jeep. Ouchy soft vehicle!

The Americans mount a flank attack from the east on turn six. Reconnaissance runs into a lone enemy tank platoon that is summarily dispatched by fire from a supporting M5 Stuart light tank. But scratch one recce jeep! Obsolete Japanese tanks are not much better than armoured cars.


Our Zoom session is running out of time. At this point the US have captured Tunga itself, and Japanese artillery fire will not drive them out. However, there are four villages along the main road to be cleared, and friendly forces have only accounted for two of them.


US E Company is sent packing by a Japanese counter-attack from the road. Note the two burning Type 95 Ha-Go light tanks that attempted an overrun. Bazookas are rather effective against light armour.

US 2nd Battalion flanking movement surprised the second Japanese infantry battalion as it moved on in road column. However, the Japanese recovered and counter-attacked, wiping out half of E Company.

Our battle at its conclusion.
As often happens, we ran out of time. We played seven turns of carnage. It was a tough fight for the US; we reckoned that they had a 50/50 chance of pulling a minor victory out of the fire if we had played to turn 12 and beyond.
