Whether it is lawful to lay ambushes in war?
Objection 1. It would seem that it is unlawful to lay ambushes in war. For it is written (Dt. 16:20): "Thou shalt follow justly after that which is just." But ambushes, since they are a kind of deception, seem to pertain to injustice. Therefore it is unlawful to lay ambushes even in a just war.
Objection 2. Further, ambushes and deception seem to be opposed to faithfulness even as lies are. But since we are bound to keep faith with all men, it is wrong to lie to anyone, as Augustine states (Contra Mend. xv). Therefore, as one is bound to keep faith with one's enemy, as Augustine states (Ep. ad Bonif. clxxxix), it seems that it is unlawful to lay ambushes for one's enemies.
Objection 3. Further, it is written (Mt. 7:12): "Whatsoever you would that men should do to you, do you also to them": and we ought to observe this in all our dealings with our neighbor. Now our enemy is our neighbor. Therefore, since no man wishes ambushes or deceptions to be prepared for himself, it seems that no one ought to carry on war by laying ambushes.
On the contrary, Augustine says (QQ. in Hept. qu. x super Jos): "Provided the war be just, it is no concern of justice whether it be carried on openly or by ambushes": and he proves this by the authority of the Lord, Who commanded Joshua to lay ambushes for the city of Hai (Joshua 8:2).
I answer that, The object of laying ambushes is in order to deceive the enemy. Now a man may be deceived by another's word or deed in two ways. First, through being told something false, or through the breaking of a promise, and this is always unlawful. No one ought to deceive the enemy in this way, for there are certain "rights of war and covenants, which ought to be observed even among enemies," as Ambrose states (De Officiis i).
Secondly, a man may be deceived by what we say or do, because we do not declare our purpose or meaning to him. Now we are not always bound to do this, since even in the Sacred Doctrine many things have to be concealed, especially from unbelievers, lest they deride it, according to Mt. 7:6: "Give not that which is holy, to dogs." Wherefore much more ought the plan of campaign to be hidden from the enemy. For this reason among other things that a soldier has to learn is the art of concealing his purpose lest it come to the enemy's knowledge, as stated in the Book on Strategy [Stratagematum i, 1 by Frontinus. Such like concealment is what is meant by an ambush which may be lawfully employed in a just war.
Nor can these ambushes be properly called deceptions, nor are they contrary to justice or to a well-ordered will. For a man would have an inordinate will if he were unwilling that others should hide anything from him
This suffices for the Replies to the Objections.
As John Locke says, "The people cannot delegate to government the power to do anything which would be unlawful for them to do themselves." You can't adhere to the proper authority requirement without rejecting the whole theory of authority behind the American revolution. That theory happens to be right. Before there was any government around to do this in an organized fashion, God said, "Whoso sheddeth man's blood, by man shall his blood be shed." Therefore, there is a duty to shed the blood of the guilty. It must inhere in the person or institution that can best carry it out, since it doesn't specify who is to do it, but says it shall be done. If you're determined to do something, you use the best means you have. Government is merely the delegation of the execution of this duty, to be a terror to doers of evil work.
The important this is a just cause. The other things are nice, but if the cause is just, the war is.
BTTT on the Memorial of St. Thomas Aquinas, Doctor of the Church, January 28, 2006!
Slavery, for example.
There are times when a people must fight, must send their best young men out to fight and die.
This is sad, but there are worse things.

Collect:
God our Father,
You made Thomas Aquinas known
for his holiness and learning.
Help us to grow in wisdom by his teaching,
and in holiness by imitating his faith.
Grant this through our Lord Jesus Christ, Your Son,
who lives and reigns with You and the Holy Spirit,
one God, for ever and ever. +Amen.
First Reading: Wisdom 7:7-10,15-16
Therefore I prayed, and understanding was given me;
I called upon God, and the spirit of wisdom came to me.
I preferred her to scepters and thrones,
and I accounted wealth as nothing in comparison with her.
Neither did I liken to her any priceless gem,
because all gold is but a little sand in her sight,
and silver will be accounted as clay before her.
I loved her more than health and beauty,
and I chose to have her rather than light,
because her radiance never ceases.
May God grant that I speak with judgment
and have thought worthy of what I have received,
for He is the guide even of wisdom and the corrector of the wise.
For both we and our words are in His hand,
as are all understanding and skill in crafts.
Gospel Reading: Matthew 23:8-12
But you are not to be called rabbi, for you have one teacher, and you are all brethren. And call no man your father on earth, for you have one Father, who is in heaven. Neither be called masters, for you have one master, the Christ. He who is greatest among you shall be your servant; whoever exalts himself will be humbled, and whoever humbles himself will be exalted.
SHORT PRAYER AFTER COMMUNION
Sweetest Jesus,
Body and Blood most Holy,
be the delight and pleasure of my soul,
